RF Transmitter datasheet and documents for STM332U
RF Transmitter Overview
The STM332U is a 902 MHz energy harvesting wireless temperature sensor module designed for the North American market. It operates on a 3V supply and utilizes FSK modulation at a maximum data rate of 125kbps. The module integrates a board-mounted whip antenna, solar cell, energy storage capacitor, and onboard temperature sensor. It complies with FCC regulations and supports EnOcean Equipment Profiles (EEP) for standardized telegrams. Operating temperatures range from -20°C to 60°C.
RF Transmitter Feature Summary
- Self-powered operation using integrated solar energy harvesting and ultra-capacitor storage
- Optimized for maintenance-free wireless temperature sensing applications
- Compliant with FCC requirements for the 902 MHz frequency band
- Supports standard EnOcean Equipment Profile telegram transmission
RF Transmitter Applications
- Wireless room temperature monitoring systems
- HVAC control panels requiring battery-free operation
- Building automation sensors in North American facilities
- Industrial environment monitoring where battery replacement is impractical
RF Transmitter Procurement Notes
Verify that the specific order matches the STM332U designation rather than similar variants like STM330 or STM331. Confirm regulatory compliance documentation for the target region. Ensure interface requirements align with the module's connector-based design. Check manufacturer specifications for minimum charge times relative to ambient light conditions.
RF Transmitter Selection Notes
Select this module when a dedicated temperature sensor with integrated energy harvesting is required for the 902 MHz band. It is suitable for applications needing long-range communication without battery maintenance. Consider the onboard antenna design if space constraints prohibit external antenna connections. Verify compatibility with existing EnOcean gateway controllers supporting EEP standards.
RF Transmitter Part Context
The STM332U belongs to EnOcean's Scavenger series of 902 MHz modules, specifically developed for the North American market. It complements other modules like the PTM210U switch and TCM300U transceiver. This component represents part of the Dolphin product line, focusing on sustainable, self-powered wireless solutions for building and home automation ecosystems.
RF Transmitter Replacement Considerations
Public confirmed substitute part numbers are not available. The STM332U is a distinct model within the EnOcean portfolio. Direct replacements may require evaluation of frequency band compatibility and energy harvesting capabilities.
