What is it?

RF-B-AR4 is an RF-star sensor-based Beacon device with a stable structure and extremely low power consumption. It supports iBeacon and Eddystone (UID, URL, TLM). The temperature & humidity sensor and accelerometer sensor make it more flexible for a wide range of applications. Without changing the battery, RF-B-AR4 can reach up to 5-year service life. The replaceable CR2477 battery achieves a longer service life.
