nodemcu - Honeywell HPMA115S0, sensor not start again ...

Jan 17, 2018· If the ESP wakes up, the sensor does not respond on commands till you remove the 5 volts of the HPMA for a short time to make an "hard reset" of the sensor. I think there is a problem with the ttl-level on the UART-RX-line of the HPMA. Because if you're pulling the rx-line of the sensor manually to ground (maby the ESP is doing this if he goes ...

The Honeywell HPMA-115 Air Quality Sensor experiment

The HPMA 115 Sensor. The Honeywell HPM Series Particulate Matter Sensor is a laser-based sensor which detects and counts particles using light scattering. The detection concentration range is 0 µg/m3 to 1,000 µg/m3. A laser light source illuminates a particle as it is pulled through the detection chamber. As particles pass through the laser ...

How to Build an Affordable Air Quality Sensor for Your Home

Jun 03, 2019· The HPMA115. The particle sensor is a bit more tricky. When it is turned on, the device starts sending particulate data on a regular interval. it’s in auto-send mode every time it powers up. I tried previously to configure the device but sometimes I wouldn’t get a response back. It was always hit and miss. It drove me crazy.
