obniz parts
0 [IR Module] Vcc
1 [IR Module] send(IR LED anode)
2 [IR Module] recv(IR Receiver output)
3 [IR Module] GND(IR LED cathode)
7 [LM35DZ] GND
8 [LM35DZ] output
9 [LM35DZ] Vcc

Software

Supply power to the obniz and run the program. The temperature measured by temperature sensor will be displayed.

Second, record your air conditioner’s signal for ON/OFF.

The example contains comment outed code for IR receiver. Remove the comment out and record your air conditioner’s ON/OFF signal. Your signal will be showed in log.

Put recorded data into the array of the infraredLed.send([]) at the “Program”(line 23).

$("#on").click(function(){
    // your value for ON here.
    infraredLed.send([])
  })
  
  $("#off").click(function(){
   // your value for OFF here
    infraredLed.send([])
  })

At last, run the program again and push tap the “ON/OFF” button.
