These radio modules come in four variants (two modulation types and two frequencies) The RFM69's are easiest to work with
Simply download our library and connect the SCL pin to your Arduino's I2C clock pin
They have a color picker
and is rated for 5W max (5V/1A) but when we plugged them in they seemed to draw more like 1
1" header is also included so you can solder it on and plug into a breadboard
Adafruit MiCS5524 CO, Alcohol and VOC Gas Sensor Breakout Sensors These radio modules come inGive your next sensor project a nose for gasses with the Adafruit MiCS 5524 Gas Sensor Breakout. This breakout makes it easy to use this nice sensor from SGX Sensortech. The MiCS 5524 is a robust MEMS sensor for indoor carbon monoxide and natural gas leakage detection, it's suitable also for indoor air quality monitoring; breath checker and early fire detection. Please note: This sensor is sensitive to CO ( ~ 1 to 1000 ppm), Ammonia (~ 1 to 500 ppm),
