OpenHAB - SmartHome

In this new video we resume the project of the swimming pool control unit by assembling a rough but functional prototype.

The components used are:

• ESP8266 NodeMCU Lolin v.3: MCU with integrated Wifi
• TDS Meter: water quality
• PH Probe PH-4205C: PH sensor
• Analog Digital Converter ADS1115: Analog digital converter to to increase the number of analog inputs of the ESP8266 (which has only one) and to improve its acquisition
• 2 x DS18B20 Waterproof temperature sensors: to get water and air temperature

I finally tested the physical and electrical connections with a relatively simple program that prints the data from the temperature sensors and the 4 analog inputs of the ADS1115 on serial.

The final goal will be to write a program to calculate the PH and TDS values ​​and send them, together with the temperature data, to the MQTT broker and then receive them on OpenHAB
