RF Transmitter Keyfob

Order No. 3158

This miniature pocket Keyfob transmitter is perfect for use with the RF Electrosmog sensor.

This is the RF transmitter we used in the `How does antenna length affect signal strength?' and `How does distance from the transmitter affect signal strength?' experiments.

The Keyfob is housed in a tough ABS enclosure and supplied with battery ready to operate. It operates at a frequency of 433.92 MHz with a range of up to 150 metres (optimum range - in direct line of sight).

It will transmit a KEELOQ code for as long as the push-button switch is depressed and has a LED to indicate transmission.
