Ein CO2Sensor nach dem NDIRMessprinzip zu einem erschwinglichen Preis ist der MHZ19B, den man bei ebay oder direkt aus China beziehen kann. Mit diesem Sensor wird über eine (5Vkompatibel laut Datenblatt) kommuniziert; man braucht also lediglich die Anschlüsse GND, Vin, Rx und Tx anzuschließen.
HM10 is a Bluetooth BLE module based on TI CC254x chip. Originally manufactured by Jinan Huamao but there are many clones in the market ( MLTBT05, CC41A, JDY08, AT09, ...) While they look similar and utilize the same CC254x Bluetooth chip, the firmware on them is different. In order to get any type of module to work work Tasmota it is ...
The MHZ19C module is a nextgeneration CO2 sensor based on the nondispersive infrared (NDIR) principle. MHZ19 C is the successor of the widely popular MHZ19 B. See below for a comparison. The MHZ19C 400~2000ppm CO2 sensor has builtin temperature compensation and communicates over UART and PWM with the host controller.
