Ultrasonic Range Sensor on the Raspberry Pi Joachim Weise

20191228· The HCSR04 sensor requires a short 10100us pulse to trigger the module, which will cause the sensor to start the ranging program (8 ultrasound bursts at 40kHz) in order to obtain an echo response. Once the 8 burst pattern is sent, the ECHO pin is set high ( 5V), and when the signal reflects and comes back the ECHO pin is set low (0V). This ...

GitHub thstielow/raspibme680iaq: Basic IAQ calculator ...

The BME680 is a metal oxidebased sensor that detects VOCs by adsorption (and subsequent oxidation/reduction) on its sensitive layer. The sensor works through a metaloxide surface, to which a voltage is applied in order to determine the resistance. By heating the oxide layer, activation energy is provided for reactions with air compounds.

A VOC Sensor Can Protect Your Health in the COVID19 Era

Volatile Organic Compounds (VOCs) are a large group of chemicals that are commonly found in homes, offices, and other indoor spaces. Once these chemicals find their way inside, they are released or “offgassed” into the indoor air we breathe. VOCs are generally measured as a cohesive group (Total VOCs); the Awair VOC sensor reacts to over fifty. VOCs are found in building materials ...
