10$ wifi temperature/humidity/luminosity sensors

SEE https://miogui.github.io/wimio...

This is a temperature/humidity/luminosity wifi sensors for plant growing.

All sensors values are automatically uploaded on iot application such as thingspeak to monitor daily/hourly changes, and logged on MQTT server.

Everything is possible with this sensor, you can display all value sent by others sensors, display yahoo forecast weather, or anything else (finance, mail, etc...)

Tutorial and Arduino code is on Github : https://github.com/miogui/wimi...

Demo is actually running with 2 module, 1 on my desktop, and 1 inside my "orchydarium": https://thingspeak.com/channel...

0.93" Oled screen : https://fr.aliexpress.com/item...

Witty cloud ESP12F : https://fr.aliexpress.com/item...

DHT22 humidity/temperature sensor : https://fr.aliexpress.com/item...

TLS2561 luminosity sensor : https://fr.aliexpress.com/item...

In order to get your wimIO working you just have to connect SCL pins (of screen and TLS2561) on GPIO5 of the esp8266, connect SDA on GPIO4 and data of DHT22 on GPIO2 with a 10k pull-up.

Software requirement:

see https://github.com/miogui/wimi...

futur improvements

• Add an example to monitor others wimIO sensors on one wimIO (already working, just need to cleanup the code)
• Add an example to monitor soil moisture, Co2, barometer(BMP085), etc...
• Add a configuration file to be able to select what you want to see and monitor (humidity/temperature/luminosity/weather/finance/alert/MQTT/thingspeak/etc...)
• Add a web-server to configure anything you want (SSID, chanel name etc...)

Desk version and deported sensors version ar comming soon !
