ESP32 Air Quality Monitor with ThingsBoard - PCB Artists

2021-03-21· The sensor returns AQI value, concentration of NO2 and O3 in a standard format, which is an ASCII string that the ESP32 can directly upload to the server as telemetry. Sending a command and receiving a reply from the sensor is very easy using Arduino code for ESP32. For example, here is how the code issues the ID command to the sensor and reads back its unique ID. // Issue ID command …

NO2 click - MikroElektronika

The sensor used on this board is the 3SP-NO2-20 gas sensor from SPEC Sensors, which can sense NO2 concentration up to 20ppm. The sensor has a very short response time, however the longer it is exposed to a particular gas, the more accurate data it can provide. This is especially true when calibration is performed. It should be noted that the sensor has a very high sensitivity to small ...

List of Arduino Sensors and Modules - The Geek Pub

This list of Arduino sensors and modules are in “module” form-factor. This means they already include things like current-limiting resistors, terminal posts, and potentiometers on-board to help you save time. While this makes creating with your Arduino simple, its not entirely necessary. For example, in lieu of the two-color LED module, you could use a two color LED, 330 Ohm resistors, and ...
