The HM-TRP-915S is a highly efficient and small-sized transponder module from Hope Microelectronics. This transponder module operates in the 315MHz frequency and supports 433MHz ASK, 315MHz OOK & 2-FSK, and 868/915MHz FSK modulation modes. It has a maximum receiving distance of up to 500 meters in open space. This miniaturized and surface-mount device is designed for use in RFID, security systems, presence detection, access control, and other radio frequency communication systems.
The HM-TRP-915S transponder module also features adjustable transmission power between 0 and 20dBm, a data rate range of up to 5Kbps, an adjustable receiver sensitivity between -103dBm and -125dBm, and a temperature range from -20°C to +70°C. It offers 3V-5.5V power supply and withstands a high humidity environment (up to 95%). This module is also RoHS and REACH compliant and certified.
