Description
The 0–25V Voltage Sensor Module is a simple, reliable, and compact module designed for voltage measurement applications. It uses a precision voltage divider circuit to safely scale down higher voltages so they can be read by a microcontroller’s analog input.
Key features:
- Suitable for measuring low to moderately high DC voltages (battery, power supply, solar panel output).
- Directly interfaces with microcontrollers like Arduino, ESP32, and Raspberry Pi (via an external ADC).
- Output is a proportional analog voltage (0–5V) that can be easily processed by a 10-bit ADC.
- Compact design makes it easy to integrate into embedded systems.
- Ideal for battery health monitoring, automation projects, and DIY IoT devices.
PACKAGE INCLUDES:
- 1 × Voltage Detection Sensor Module (0–25V)
