The STM100 is a small solar-powered wireless sensor module designed for efficient wireless sensing.

The STM100 handles creation, storage, and management of power. Within its custom two-stage solar cell, one stage provides quick start-up energy, while the other charges an on-board energy reservoir. Designed to operate indoors, the device requires only 200 lux to generate energy. (Typical lighting values in a building are 200 lux in hallways, 500 lux on desktops, and up to 1,200 lux in display cases.)

The unit comprises a solar cell energy source, an energy reservoir, analog and digital sensor connections, a microprocessor for sensor control, and a radio transmitter—all of which are packed in a 0.8² × 1.6² × 0.4² footprint. Despite its small size, the STM100 stores sufficient energy to operate continuously for up to five days in complete darkness. The module assures reliable wireless communication via sophisticated RF protocols: multiple broadcasts, fast data rate, error detection, and unique addressing.

The STM100 offers three analog and four digital inputs along with measurement routines. OEMs can quickly create a completely self-powered, functioning, communicating device for remote installation.

To simplify the development of wireless networks, a family of receivers and transceiver/repeaters that is compatible with the company’s switch and sensor modules is available. The proprietary radio technology is approved for use in Europe (ETSI), the United States (FCC), and Canada (IC).

The STM100 is available in OEM quantities for less than $25.
