My own indoor Sensor

By admin No comments

EVE whether broke:( so i decide to make mu own sensor. I just use eve cover for Aliexpress stuff.

It’s messure PM2.5/PM10, Temperature, humiditi, air pressure, light level.

ESP8266 – 3€
BME280 – 4€
GY-302 – 1€
PMS7003 – 10€

ALL: 18€ and of course my IndoorSensor firmware:)
More supported hardware You can find here:http://dziky.pl/homekit/homekit-indoorsensor-1-0-1/

Wiring is simple:
BME280 and GY-302 both connect exactly the same

VCC to 3.3V on ESP
GND to GND on ESP
SCL to D1 on ESP
SDA to D2 on ESP

PMS connect
VCC to 5V on ESP
GND to GND on ESP
TX to D6 on ESP
RX to D7 on ESP

Here is comparison my sensor based on PMS7003 and Kaiterra Laseregg 2 all messurments are almost identical.

Without cover

Unfortunately, when closed in the eve box measurements are less accurate. PM are differ from real values, temperatures is over by 3 degrees (can be set in offset so no problem).
I’m working on 3D printed cover for better air flow.
