Hello, I'm hoping someone with more experience than me (i.e. everyone) can offer some advice.
A project I'm working on requires the wireless transmission of ultrasonic sensor data (around 40kHz) over a very short distance (< 3 meters).
We are currently looking to utilize commercially available FM TX/RX IC's to implement this function. As I'm very new to wireless/RF I've been having trouble wading through the wealth of IC offerings on sites like DigiKey.
Transmission only needs to occur when the sensors register an event in the 40kHz range, so it would be ideal if the FM IC featured some form of sleep/wake function (to minimize power consumption as these devices will be battery operated.)
Does anyone know off-hand of a manufacturer who makes a chip with these features (i.e. accepts ultrasonic modulating frequencies and has a sleep function)?
Thanks
