Energy harvesting wireless sensor module

Specifications

EnOcean STM300 : Energy harvesting sensor module

STM300 features an energy harvesting interface for the implementation of self-powered products. The minimal standby power consumption makes it especially suitable for energy harvesting wireless solutions such as bidirectional temperature sensors, sensors in building services and innovative actuators. STM 300 can be powered by a solar cell, available in two sizes - ECS300 and ECS310.

Features :

- 3 A/D converter inputs
- 4 digital inputs
- Configurable wake-up and transmission cycle
- Wake-up via Wake pins
- Voltage limiter
- Threshold detector
- Application notes for calculation of energy budgets and management of external energy storages
