10$ wifi temperature/humidity/luminosity sensors

pinshape

SEE https://miogui.github.io/wimio This is a temperature/humidity/luminosity WiFi sensor for plant growing. All sensor values are automatically uploaded to an IoT application such as ThingSpeak to monitor daily/hourly changes, and logged on an MQTT server. Everything is possible with this sensor. You can display all the values sent by other sensors, display Yahoo forecast weather, or anything else (finance, mail, etc...). Tutorial and Arduino code are on GitHub: https://github.com/miogui/wimio Demo is actually running with 2 modules - one on my desktop, and one inside my "orchydarium": https://thingspeak.com/channel/12345678 BOM: 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 the SCL pins (of the screen and TLS2561) on GPIO5 of the ESP8266, connect the SDA pin on GPIO4, and the data pin of the DHT22 on GPIO2 with a 10k pull-up. Software requirements: See https://github.com/miogui/wimio Future improvements: Add an example to monitor other 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, channel name, etc...) Desk version and deported sensors version are coming soon!
