Engineer Greg Cormier has designed an Espressif ESP32-powered board which goals to make it straightforward to get Plantower PMSx003 and Panasonic NA-GCJA5 specific matter (PM) air high quality sensors speaking to a House Assistant occasion: espairqual.
“Espairqual is an ESP32 based mostly ESPHome interface for PMSx003 and Panasonic NA-GCJA5 particulate matter (PM) sensors,” Cormier explains of the machine he has designed. “It presents a plug and play answer to combine air high quality monitoring with house assistant. It offers 5V to the sensor and three.3V to the interior electronics.”

Pushed by an Espressif ESP32 module operating the favored ESPHome firmware, the board is designed to speak to one of many two totally different air high quality sensors: “Whereas the [Plantower] PMS5003 is an effective sensor,” Cormier explains of his resolution so as to add help for the Panasonic sensor, “I did obtain one dead-on-arrival from Aliexpress. The Panasonic sensor is cheaper, smaller, obtainable from tier-1 distributors and has a 5+ 12 months life expectancy.”
In both case, the board connects to the exterior sensor and acts as a bridge to a House Assistant or appropriate house automation system. A USB Sort-C connector is used for energy, driving each the espairqual board and the sensor to which it is linked, or there are screw terminals for DC and AC energy — from 9VDC as much as both 40VDC or 28VAC, with 24VAC because the goal for the design.
Cormier has launched board design information and supply code for the challenge on GitHub beneath an unspecified open supply license; assembled boards can be found to order on his Tindie retailer at $30, and match inside a Hammond 1593KBK case to neaten issues up.
