RF4 and Next Generation Sensors
Next Generation Devices
We are happy to announce our next-generation RF products with improved battery life and support for over 15M device IDs per installation using our RF4 encoding. Our next-generation WiFi devices are based on the ESP32 processor, offering more options and secure data connections.
RF4
Our RF4 encoding allows the device ID to be increased from the older RF2 or 2 Numeric ID to 4 Character ID using RF4 encoding. The allowable character set is now not just numbers 0-9, but also includes lower-case a-z and upper-case A-Z in almost any combination.

Datasheet
High-performance RF transceiver based on the market-leading CC1101 using a one-to-many broadcast protocol with each device having a 4-character ID
- Excellent receiver selectivity and blocking performance
- High sensitivity 30M range
- Very fast transition times from sleep modes to active mode enable ultra-low average power consumption in low duty-cycle systems(0.3 µA operating mode with the lowest power consumption setting)
- AES-128 encryption co-processor provides robust and secure radio link
- Built in packet handling hardware
- Support for multiple frequencies in license-free ranges (e.g.Europe 433MHz, 863-870MHz, USA 902-928MHz)
- Excellent receiver selectivity and blocking performance improve range and reduce interference in radio-congested urban environments
- automatic whitening and de-whitening of data
- automatic modulation and demodulation of data
- The received RF signal is amplified by the low-noise
amplifier (LNA)
- Automatic gain control (AGC), also called automatic volume control (AVC), to provide a controlled signal amplitude
