Figure 1 Simple circuit to indicate a low battery. For this application, the LED proved to be a decent reference diode. It has a temperature coefficient that tracks fairly well with that of Q1, and ...

The development kit supports a host of peripherals including an LTE-M1/GNSS module, temperature sensor, and a 3-axis accelerometer for developers creating a broad range of IoT projects.

By combining and adapting various different materials, thermal management could be optimised for battery module safety.

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device.
