This instructable shows how to build a rather special pool sensor measuring the pool temperature and transmitting it via WiFi to Blynk App and to a MQTT broker. I call it the “Crocodile Solar Pool Sensor”. It uses the Arduino programming environment and an ESP8266 board (Wemos D1 mini pro). What’s so special about this project?

The global population increased at its fastest rate in recorded history during the twentieth century, rising from around 1.6 billion in 1900 to over 6 billion in 2000. And due to the rising population, the energy demand has also increased exponentially. Therefore, the world is facing two potential threats. The first is undoubtedly climate change
