Description
Description Stable performance Wide operating voltage range Good product consistency and high cost performance The on board coding chip is easy to use Technical parameter Working voltage DC3 9VWorking frequency 433MHZ optional Standby current 0mAWorking current 15mACoding method Fixed codeTransmission distance 500m opening board sensitivity is above 103dBm Output power 15dBm 32mW Transmission rate 10KbpsModulation method OOK amplitude modulation Working temperature 10C 70CSize 36238mmPINNAMEFunction113Data pin212Data pin311Data pin410Data pin5VCCPower 6GNDPower 7ANTAntenna endPrecautions for use 1 Use a flexible wire or other hard metal such as a whip antenna for the antenna to a length of approximately 28 cm 315 MHz 24cm 433MHz and use it as straight as possible Do not approach metal objects 2 The power supply voltage is stable and the ripple factor is low Multi stage filtering is required such as adding beads inductors capacitors etc 3 If the MCU clock frequency is below 4MHZ and the crystal is as far away as possible from the RF receiver module the higher harmonics of the crystal will affect the communication distance 4 Note that the rate of the encoding IC and the decoding IC is the same and the format of the code is the same that is the oscillating resistance is matched otherwise the distance will be affected and the communication will not be possible Package includes 5 x Receiving Board
