The Low Cost pH Sensor PCB Type with Level and LDR is a compact, multi-functional sensor module engineered to measure the pH value of liquids while simultaneously monitoring light intensity, temperature, and water level.With some calibration this sensor can give proper readings as per your scale. Designed for Arduino, Raspberry Pi, ESP32, and other microcontroller platforms, it communicates via TTL UART using a 9600 baud rate, making it perfect for integration into IoT-based projects with Arduino, Raspberry Pi and Other controllers.

Features:

• pH Measurement: Detects hydrogen ion activity to determine acidity or alkalinity (0–14 pH)
• LDR Sensor: Monitors ambient light intensity using a light-dependent resistor
• Temperature Sensor: Measures environmental temperature levels
• Water Level Sensor: Detects water presence or level using a level detection circuit
• TTL Communication: Standard TX/RX pins for serial communication at 9600 baud
• Wide Compatibility: Works with Arduino, Raspberry Pi, AVR, STM32.
