This circuit integrates various sensors with an Arduino UNO R4 WiFi microcontroller to measure environmental parameters such as temperature, TDS (Total Dissolved Solids), and pH levels. The sensors are powered by the Arduino's 5V output and share a common ground. Sensor outputs are connected to the Arduino's analog and digital inputs for data acquisition. A resistor is used in conjunction with the DS18B20 temperature sensor for signal conditioning.
