The Kimat – Voltage Sensor module is a 4 channel voltage divider network for sensing of voltages from 0V24V (for 5V controllers) via ADC. This simple circuit aims to facilitate quick and hassle-free implementation of direct reading of voltages over the I/O voltage limit of ADC’s by scaling the input voltages with resistors without soldering. The Kimat – Voltage Sensor is part of Layad Circuits’ Kimat series of rapid prototyping products.

The Kimat-Voltage Sensor module is nothing more than 4 voltage divider networks with input and output headers. Any input voltage is scaled down by a factor of 47/247 to facilitate safe measurement of voltages. The module was created for use with the ADC of microcontrollers. While the circuit may be simple, implementing up to four channels may be time consuming. Hence, this module was created for the quick implementation of up to 4 voltage sensing channels for ADC’s.
