Environment data station build with ESP8266 NodeMCU using: 1. GY-21-Si7021 (outdoor temp & hum) 2. DHT21 (indoor temp, hum) 3. DS18B20 (heating water temp) 4. CCS811 (indoor air quality eCO2 and TVOC)
Beta V1.0 Monitoring indoor temperature, o/c windows, battery status and CO2
Temperature measurement (°C) inside a 30L/~8 gallons aquarium. Temperature sensor: DS18B20 Microcontroller: NodeMCU v1
esp8266 collect outdoor temperature from Dallas ds18b20 and indoor temperature acompany with atmospher pressure from BMP180 sensor. OpenWRT + Mosquitto + Node-Red used for aquisition and publish the data.
