Wireless Sensor Connectivity description

The AS3930/32/33 are a family of ultra-low power, low-frequency wake-up receivers which operate in the frequency range 15-150kHz. They include built in correlators to detect 16- or 32-bit programmable wake-up patterns, and offer the choice of 1 or 3 receive channels depending on the requirement to support a fixed or variable orientation between transmitter and receiver.

The AS3935 Franklin lightning sensor estimates the distance to the leading edge of a lightning storm. It detects both cloud-to-cloud and cloud-to-ground lightning. It is ideal for consumer grade, battery operated devices for outdoor weather stations, or for leisure activities such as hiking or golf.
