20170127· [I asked this question on the Arduino Stack Exchange, and I waited a while and got no answer, so I thought that I''d ask it here!]. I want to integrate Pololu''s vl53l0x Time of Flight distance sensor into a project of mine. They created a library to interface with the vl53l0x over I2C, which works great on my Uno. The only problem is that doesn''t work on the ATtiny85.

Arduino | Adafruit SCD30 NDIR CO2 Temperature and ...

20210725· The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor, that will tell you the CO2 PPM (partspermillion) composition of ambient air. Unlike the SGP30, this sensor isn''t approximating it from VOC gas concentration it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

atmospheric carbon dioxide sensing with an Arduino ...

20180618· The MHZ16 NDIR CO2 Sensor costs and comes with a UART to I2C adapter. This makes powering it and communicating with it quite simple: just connect four wires to the development board of your choice! I used an Arduino Nano to read the values from the sensor and send them to the laptop over the USB connection that was also powering it. The ...

Gravity UART IR CO2 Sensor sample code

20200730· My sensor is the MHZ16 and is capable of 50,000 ppm. i will need to measure more than 5k ppm. i really need some help here. From my reading of the data sheet, the 1004ms pwm output is scaled to the range of your sensor. If you have purchased the 050000ppm (05%) sensor, then that is what the output should reflect.

Gravity: Analog CO2 Gas Sensor For Arduino (MG811 Sensor ...

Here is the Arduinobased CO2 sensor designed by DFRobot lovely engineer. This is the first CO2 sensor in the Arduino market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (the voltage is lower than the threshold), a digital signal (ON/OFF ...
