SEN0159 by DFRobot | Sensor Development Boards and Kits ...

The SEN0159 by DFRobot is the first carbon dioxide sensor on the OSHW market. This sensor's operating principle is straightforward: as environmental CO2 concentration increases, the output voltage of the sensor decreases. The SEN0159 emits a signal whenever the output voltage falls bellows a certain threshold (CO2 is above a certain threshold).

5V analog sensor to a 3v3 MKR1000 - Sensors - Arduino Forum

May 06, 2021· Should I use a voltage divider circuit with two resistors to drop the analog 0 to 5V signal from a DFrobot SEN0159 CO2 sensor that I intend to connect to an analog pin on my brand spanking new MKR1000 board? I ordered a four channel bi-directional level shifter for the I2C bus connection to the LCD, but it's my understanding these are for digital signals, not analog.

SEN0159 - Analog CO2 Gas Sensor for Arduino Development …

Gravity analogue CO2 gas sensor for Arduino (MG-811 sensor) 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 on-board 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) will be released ...
