Rebooting the HPMA115S0XXX

Jan 04, 2020· The HPMA115S0 says it draws at 5V. That leaves for the display, voltage converter and Arduino Uno. An Uno (rev 3) board apparently draws about 50mA. The backlight on the LCD can wolf down up to 160mA, and the LCD driver itself eats about 20mA. Subtracting those estimates leaves 50mA unaccounted for.


The dust sensor is now finally working | MySensors Forum

Mar 06, 2017· vladimir said in The dust sensor is now finally working:. alowhum Hello! In what range of values is the norm for living space? My sensor shows 17 units. Hi Vladimir, my recommendation is to not use that sensor and take a better model instead, like Plantower PMS5003 or PMS7003. Their claims of accuracy are a bit overrated by Plantower IMHO, but they are way more accurate than those "dust ...

A code library for HPMA115S0 particle sensor

Mar 19, 2019· The HPMA115S0 sensor requires 5V power, but it uses logic levels on TX and RX lines. As such, a logic level converter like BOB12009 is required when using the sensor with 5V boards like Arduino Uno and Mega, as I did in this blog post. On boards like Arduino Due, the TX and RX lines can be directly connected to the board.
