Propane tank level as measured by a ratiometric hall effect sensor mounted over the tank's analog dial gage. Uses an Arduino Mini Pro and an ESP8266 Wi-Fi module, powered by a 3.2V LiFePo4 battery and solar cell.

Room temperature,humidity and heat index test DHT22 sensor and ESP8266

K-Type thermocouple running through a MAX6675 interface to an Arduino UNO. Wifi connected via a Sparkfun ESP8266 Thing board.

Particle Photon DHT22 DataStream

Arduino + 4 DS18B20 + LCD

Arduino Temp sensor

Sensores Quarto

PulseSensor connected to Arduino Nano along with algorithm code to read pulses from sensor then formulate BPM and send BPM values to NodeMCU ever Minute. and the nodeMCU with Lua firmware waits for BMP data, once received it updates BPM values to ThingSp

Using a NanoESP (Arduino compatible Nano and a esp8266) to send Brightness. More Info see http://iot.fkainka.de/day-19
