ESP8266 with I2C Arduino Slave and MQ-2 & MQ-7 Gas Sensors, with SHT21 Temp & Hum sensor posting via Mobile 4G / WiFi

ESP8266-01 + BME280 + 5V 60mA Solar Panel + 2x AA NiMH rechargeable batteries https://github.com/preechaim/esp8266-bme280-ts

BME280, DS18B20, BH1750, DHT11, ESP 8266, SSD1306, ATTINY13A, FS1000A

Temperature and humidity in Antonovo, Bulgaria. Temperature is measured by two Dallas DS18B20 temp sensors and DHT11 is used for Relative Humidity, the data is sent through ESP8266.

Currently, this Nodemcu is used to measure the capacity from recycled 18650 notebook batteries. Values maybe empty before new battery start.

Soil moisture of my benjamin into my test lab. First try with the ESP8266.

Pure Imagination is a working prototype of a future wherein plant fed microbial fuel cells cleanly generate a substantive amount of people’s daily electricity usage. This channel is regularly fed performance data of two microbial fuel cells.

Air Quality Sensor with ESP8266 and Si7021 and MQ135 for CO2

This channel displays temperature and humidity data collected by the DHT11 sensor. The arduino Uno MCU is used to process sensor data while the ESP8266 WiFi module is used to log the data to this Thingspeak channel. http://www.nandgeek.com/about
