Fermion: MEMS Nitrogen Dioxide NO2 Gas Detection Sensor (Breakout, 0.1-10ppm) SF_GNSS Antennas excellent efficiency

excellent efficiency

Sporting a matrix of 64 (8 x 8) RGB LEDs and powered directly from the Pi this is the most compact pocket aurora available

except for tools: you will need a soldering iron

It uses a small integrated slide switch to control a high-side power MOSFET that can deliver continuous currents up to around 16 A at 4

Lower Position Limit: -22

Fermion: MEMS Nitrogen Dioxide NO2 Gas Detection Sensor (Breakout, 0.1-10ppm) SF_GNSS Antennas excellent efficiencyFermion: MEMS Nitrogen Dioxide NO2 Gas Detection Sensor employs state of the art micro electromechanical system (MEMS) technology, endowing the sensor with compact dimensions (13x13x2. 5mm), low power consumption (20mA), minimal heat generation, short preheating time, and swift response recovery. The sensor can qualitatively measure the concentration of nitrogen dioxide gas, and is suitable for nitrogen dioxide detector, automobile exhaust detection,
