Enviro pHAT - temperature, humidity, pressure, light, gas, ADC sensor with microphone - HAT for Raspberry Pi

Overlay forRaspberry Piequipped withBME280temperature, pressure and humidity sensor,LTR-559light and proximity sensor,MICS6814analogue gas sensor, ADCADS1015converter, MEMS microphone and0.96"colour LCD display. There is also a connector forPMS5003sensor on the board. The cover plate is fully compatible with 40-pin GPIO connector of Raspberry Pi miniature computer.

The Enviro cap is sold separately.Raspberry Pimini computer can be purchased.

Enviro overlays are designedto testroomconditions. Temperature, humidity, light and volume sensors, as well asan LCD displayand a distance sensor for interaction allow you to create a small device for measuring the conditions in your home. The overlay can also be combined withvoice assistantssuch asAmazon AlexaorIFTTTto tell you what the current temperature is or change the brightness level of a Philips Hue bulb.

The Enviro + Air Quality overlay has been developed in collaboration withthe University of Sheffieldto read real-time air quality data in your area for projects such asLuftdaten. Devices such as Enviro enable you to obtaindetailed datathat allows you to see changes in air quality over time and in different areas of cities. More available data sharing devices will allow you to create a more detailed dataset from more locations.

The module is equipped witha number of sensorsthat allow you to read basic air quality data and prevailing conditions. In addition, the cap has been equipped with connectors to connect the PMS5003 sensor, which extends the capabilities of the project to PM measurement in the air. The manufacturer has prepared auser guidewhich shows how to use the Enviro cover plate.
