# Notes on Tuya Air Quality Sensors

![Tuya PM2.5, PM10, CO2, CH2O Air Quality sensors (Zigbee and WiFi))](https://kaspars.net/wp-content/uploads/2022/04/tuya-air-housekeeper-pm-box-scaled.jpeg?strip=all&quality=90&resize=2560,1920)Tuya 4in1 PM Box (Smart Air box) with [CB3S module](https://developer.tuya.com/en/docs/iot/cb3s?id=Kai94mec0s076) (Wi-Fi) on the left (blue case) and Tuya 6in1 Air House Keeper with [ZT3L module](https://developer.tuya.com/en/docs/iot/zt3l-module-datasheet?id=Ka438n1j8nuvu) (Zigbee) on the right (white case).These are two devices ([AliExpress](https://kaspars.net/go/tuya-air-quality-sensor-box)) with identical PM2.5/PM10 sensors (boxes with the metal cover), temperature and humidity sensors (top center) which are connected to an [STC 8G1K08 microcontroller](http://www.stcmicro.com/stc/stc8g1k08.html) which prepares the data for the Tuya controllers with either WiFi or Zigbee radio (bottom left). The 6in1 version has an additional VOC sensor (bottom right with the metal mesh) which provides VOC and *derived* or virtual formaldehyde and CO2 values.

They cost around $25 for the 4in1 version and $30 for the 6in1. I bought them [here on AliExpress](https://kaspars.net/go/tuya-air-quality-sensor-box).

## Home Assistant Compatability

The Zigbee version is known as [TS0601 Smart Air House Keeper by Zigbee2MQTT](https://www.zigbee2mqtt.io/devices/TS0601_smart_air_house_keeper.html) (`TZE200_dwcarsat`) and is supported by [their Home Assistant integration](https://www.zigbee2mqtt.io/guide/configuration/homeassistant.html) as well as the [ZHA integration](https://github.com/zigpy/zha-device-handlers/issues/1313) (except for [this bug](https://github.com/zigpy/zha-device-handlers/issues/1406)). It is also supported by the [Zemismart gateway](https://kaspars.net/blog/zemismart-zigbee-homekit-hub) in the Smart Life app but it *does not* show up in the Apple Home app.

The WiFi version is supported only by the [Tuya cloud integration in Home Assistant](https://www.home-assistant.io/integrations/tuya/) and the Smart Life app which detects the device via Bluetooth and then lets you configure the WiFi settings.
