DATA SHEET V1.1 Sensor Transmitter Module STM 330 / STM 331 / STM 330C STM 332U / STM 333U The extremely power saving RF transmitter module family STM 33x of EnOcean is optimized for realization of wireless and maintenance free temperature sensors, or room operating panels including set point dial and occupancy button with a minimum number of external components. The mod- ule provides an integrated calibrated tem- perature sensor. Type Ordering Code Functional Principle STM 330 S3001-D330 Power supply is provided by a small pre-installed STM 331 S3001-D331 solar cell, an external energy harvester, or an STM 330C S3031-D330 external 3V battery. STM 332U S3051-D332 An energy storage element is installed to bridge STM 333U S3051-D333 periods with no supply from the energy harvest- In case of no relevant input change a redundant er.

Features Overview Power supply Pre-installed solar cell Antenna pre-installed whip or helix antenna Frequency 868.3 MHz (STM 330) / 315.0 MHz (STM 330C) / 902.875 MHz ( STM 33xU) Radiated output power STM 330 / 331: typ. 8 dBm / 5 dBm (EIRP) STM 330C / STM 332U / 333U: typ 92 dBV/m / typ. 101 dBV/m / 99 dBV/m Data rate / Modulation type 125 kbps / ASK Start-up time with empty energy storage typ. <2.5 min 400 lux, 25 C 1 Initial operation time in darkness 25C typ. 4 days, if energy storage fully charged wake-up every 100 s, transmission every 1000 s on average Input Channels Internal: temperature sensor, LRN button External via 20 pin connector: occupancy button, set point dial, HSM 100 Temperature sensor Measurement range 0-40 C, resolution 0.16 K Accuracy typ. 0.5 K between 17 C and 27 C, typ. 1 K between 0 C and 40C Transmission indicator 1x LED EnOcean Equipment profiles configurable EEPs: A5-02-05, A5-10-05, A5-10-03 and with HSM 100: A5-04-01, A5-10-10, A5-10-12 Module dimensions 43 x 16 x 8 mm 1 Operating temperature -20 up to +60 C 1 Full performance is achieved after several days of operation (up to two weeks) at good illumination level. Performance degrades over life time, especially if energy storage is exposed to higher temperatures. Each 10 K drop in temperature doubles the expected life span.
