HX19R series: Ultrasonic Position Receiver
The hx19r12-IP42, is the standard hx19 receiver offered with the evaluation system. This unit is designed for indoors operation. It times the flight of the longitudinal ultrasonic wave, and decodes the identity of the incoming RFID and USID (ultrasonic identification). The distance to the RFID (ultrasonic) transmitter is measured with a resolution of 1mm. And the result from each time of flight acquisition cycle is either stored in ring buffers for delayed polling, or broadcasted as it comes over 2.4GHZ RF channel. Indefinite number of receivers can be used to monitor the position of transmitters. I.e. the more receivers monitoring the more accurate is the position. This device comes in two versions one with a pigtail lead for a power supply, and the other with internal battery.
