introduction: PIC-GSM is excellent board for adding remote monitoring and control in remote places by gsm cellular network or ethernet or internet network. do you want to switch on/off your local heating in your mountain house? to monitor the temperature at up to 8 remote points up to 30 meters away from the module? to listen what happens in your house with silent call after you get message for alarm status? then PIC-GSM is the board for you! it contains pic18f97j60 microcontroller and 3-band gsm gprs module 900/1800/1900mhz inside which covers most used gsm networks around the world. the gsm antenna is build in the board so no need for external expensive gsm antennas. PIC-GSM have two relays 240vac/10a, two opto-isolated inputs which could be connected to alarm sensors or just buttons for user actions (like call pre-loaded phone numbers), on-board temperature sensor and connector for additional up to 8 addressable remote temperature sensors at up to 30 meter distance from the module. normal phone hook can be connected to this board and to allow user to speak, listen, taking and placing phone calls as normal stand alone cellular phone. PIC-GSM can be connected to pc with the usb connector it have and it is recognized as modem which could be used to add internet via gprs to your computer (imagine how useful is this for your mountain house if there is no internet but only cellular network!). if you have internet connection you can monitor the same parameters on the web page. board features: ? icsp/icd connector for programming and debugging with pic- icd2, pic-icd2-pocket, pic-icd2-tiny; usb 2.0 type b connector allow board to be interfaced to pc host; ? gsm/gprs module 900/1800/1900mhz; ? li-ion backup battery; ? pic18f97j60-i/pt; ? ethernet rj45 isolated connector. ? gsm audio in and out; ? rs232 connector; ? quartz crystal 20mhz; ? two relays 10a/250vac; ? two digital inputs; ? analog input; ? temperature sensor; ? 5v voltage regulator; ? ext connector for available gpio; ? four mounting holes 3,3 mm (0,13"); ? fr-4, 1.5 mm (0,062"), green soldermask, white silkscreen component print; ? dimensions 124x90 mm (4880 x 3540 mils); electrostatic warning: the PIC-GSM board is shipped in protective anti-static packaging. the board must not be subject to high el ectrostatic potentials. general practice for working with static sensitive devices should be applied when working with this board.

board layout: power supply circuit: the power supply of PIC-GSM could be done in two different ways: 1. power from +12vdc without using the internal backup battery. the module is powered only from external 12v and the battery is not connected. in this case: ? jumper bat_e must be open ? jumper 4v_e must be closed ? jumper 4v_vbat must be closed ? jumper 5v_chg_e must be open. power consumption in this mode is: ? about 240ma when have a conversation. ? about 90ma in normal mode (without conversation) and active web interface + 60ma if relays are turned on. important : 4v_e, 4v and 5v_chg_e jumpers have to be moved together. 2. power from +12vdc with backup battery. the module is powered with battery and allows battery charging. in this case: ? jumper bat_e must be closed ? jumper 4v_e must be open
? jumper 4v_vbat must be open ? jumper 5v_chg_e must be closed ? power consumption in this mode: depend on the battery charge may vary between 90ma and 300ma. ? if the 12v power supply is missing the battery discharge current depend from activated microcontroler modules. max current consumption reach up to 500 ma when all microcontroler moduls are switched on and have a conversation. reset circuit: PIC-GSM reset circuit is made with rc group and optional stm1001r chip with typical threshold +2.63v. by default stm1001r chip is not assembled clock circuit: quartz crystal 25mhz is connected to pic18f97j60.

available demo software: 2. software notes software, that PIC-GSM board is shipped with, includes microchip tcp/ip stack is combined with simple functionality for making calls and sending sms with sim300d gsm/gprs module. this note explains features of PIC-GSM board. for more information on the microchip tcp/ip stack, please re fer to application note an833 available at http://www.microchip.com . sms sending functionality is strongly de pendent of serial communication between pic18f67j60 mcu and sim300d module. conseq uently board software functions are very sensitive to any messages send from si m300d module. for example, when sim300d module goes to specific states(power down, call ready etc), it sends indicating messages via serial line, which can affect commun ication with pic18f97j60 and cause wrong behavior of software. specific features: ? first time you insert power to board usb should not be connected to board due to initialization procedures between pic and gsm module. ? uart baud rate, which ensures best perf ormance is 115200 bps. other specific features, which software rely on are: ? disable echo(command used is ate0) ? set sms text format (command used is at+cmgf=1) ? after board power-up software continuously sends ?at? command expecting ?ok? string, ensuring proper communication with gsm module. ? software allows to dial gsm and make gsm call, getting gsm number or sms text from web page form. gsm numb er length is 16 digits ? software allows sending sms getting gs m number and sms text from web page forms. gsm number must be typed with country code without ?+? sign. gsm number length is 16 digits and sms message length 32 digits. ? status page item ?open call? displays information about call processing .?0? indicates that no call is in process. ?1? indicates that gsm call is in process. (after gsm number is dialed, ?open call? value is se t to ?1?, if other side close call after a while ?open call? value returns back to ?0?. if other side accept call, ?open call? value remains ?1?, for the time of call is in process. when call is closed ?open call? value is set back to ?0?) ? PIC-GSM board has 2 audio channels ? one connected to mic, and auxiliary connected to handsfree. you can switch to next audio channel by pressing button b1. ? pressing button toggle the on board buzzer unless the gsm module is not in open call mode. ? when you plug usb cable to the board, the ftdi chip on the board emulates virtual com port and you can connect to sim300d module with hyperterminal. first however have to install ftdi drivers available on the http://www.ftdichip.com/ ? temperature, displayed on web page is read from sim300d module with at command (at+cmte?). any problem with corr ect displaying temperature, is related with correct handling of used at command output or gsm module response. this measurement should not be treated as reliable . ? another useful feature is ability of getting temperatures from up to 8 external temperature sensors tcn75a connected via i2c interface. in "temperature sensors presence" each item stands for presence of sensor with given hardware address 000 for temp sensor 1, 001 for temp sensor 2, ... and 111 for temp sensor 8. "temperature measured by sensors" section contains temperature in c measured by sensor(s) available. ? items: relay 1, relay 2 and led buttons from ?status? section display voltage applied to corresponding input/output 1- high voltage; 0 ? low voltage.
log ?1? of relay1 (pg7) and relay2 (pg6) ou tputs means that the relay is turned on, while log ?0? mean that the relay is turned off. log ?1? to the led output (pg5) means that led is turned off, while log ?0? mean that the led is turned on. logical ?1? on opto input 1(rg3) and opto input 2 (rg4) means that high voltage is applied to the input ? status page item ?seconds? displays seco nds elapsed from program start, measured by rtc. ? status page item ?uin? displays input voltage in volts, measured on ra5(an4) pin . ? ?test board area? section is not intended for user examination and shouldn't be used by customer. advices to customer for further use: ? user should be familiar wi th basic at commands(make call, send sms, read sms etc). ? sim card, you put should be with disabled pin code use. so befo re use, put sim card in normal gsm and disable pin code use.
