RFM22B is a low-cost ISM transceiver module which offers
communication at 433/470/868/915MHz frequency band. It has low receiver
sensitivity (-120 dBm) and it provides +20dBm output power which ensures the
extend range for wireless communication.
It supports data rate up to 256 kbps. It has low power mode which helps in
reducing the power consumption. It has integrated low power detector to monitor
battery level of a rechargeable battery. It has additional features such as an
automatic wake-up timer, automatic frequency calibration, preamble detection
which allows it to use a low-cost microcontroller.
It operates on supply voltage range of 1.8 V to 3.6V.
It is used for applications such as Tag readers, Health monitors, Sensor
networks, Industrial control, Home automation, Remote keyless entry, Remote
meter reading etc.
