Summary of the Circuit
The circuit in question appears to be designed for water quality measurement, specifically for measuring the Total Dissolved Solids (TDS) using a TDS sensor. The sensor's data is likely to be processed by an ESP32 microcontroller, which is a versatile board with WiFi and Bluetooth capabilities. The circuit includes a TDS sensor, a Sonda Sensor TDS, and an ESP32 microcontroller.
Component List
Sonda Sensor TDS
- Pins:
+,- - Description: This component is likely a probe or an interface for the TDS Sensor, facilitating the measurement of TDS levels in water.
TDS Sensor
- Pins:
P1,P2,+,-,A - Description: The TDS Sensor is responsible for detecting the total dissolved solids in the water. It has power pins (

Documented Code
No code has been provided for the microcontroller. In a typical application, the ESP32 would be programmed to read the analog output from the TDS Sensor, process the data, and then either display it locally or transmit it for remote monitoring. The code would initialize the analog-to-digital converter (ADC) on the ESP32, read the sensor value from the corresponding GPIO pin, and apply any necessary calibration or conversion to obtain the TDS measurement. Without the actual code, we cannot provide further documentation on the software aspect of this circuit.
