Wireless RF Kit 433 Mhz (Transmitter+Receiver)
EGP 110
See other suppliers →Description
The kit is consisted of transmitter and receiver, very popular for remote control.They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Putting an antenna on either the RX or/and TX will further extend the range. The tiny copper wire (spiral) on the unit is an inductor, not an antenna. Solder a wire of length about 17.3cm to both transmitter and receiver into the antenna hole. This wire is your antenna (check photo below). Specification Frequency: 315 Mhz. Modulation: ASK Receiver data output: High - 1/2 Vcc, Low - 0.7v Transmiter input voltage: 3-12V (high voltage = more transmitting power) Transmitting range (work at 5V): 40m indoor, and 100m in open air Pin Connection (Transmitter) Vcc: 3: 12 VDC GND: Ground ATDAT: Data (connect to arduino uart Tx) Pin Connection (Receiver) Vcc: 3: 12 VDC GND: Ground DATA1: Data (connect to arduino uart Rx) DATA2: Data (connect to arduino uart Rx, use any of them) Tutorial on how to use with Arduino More tutorial on how to use with Arduino
