Taidacent 85 115MHz FM Transmitter Module Microphone Patient Monitoring Wireless Micro FM Transmitter FM Radio Transmitter

Product Overview

Description

Taidacent 85-115MHz FM Transmitter Module Microphone Patient Monitoring Wireless Micro FM Transmitter FM Radio Transmitter

Introduction

Dimensions	Length 2 cm * Width 1cm
Operating voltage	DC 2V --- 9V (recommended battery-powered, power supply will have a steady flow)

  

The voltage affects the distance, the closer the voltage is, the closer

 

Working current: 9ma (3V voltage test, super power saving)

 

Reference distance: 100 meters open, indoor obstacle environment 10-30 meters (3v voltage test, improve the voltage distance greatly improved)

 

Operating frequency: 85MHZ --- 115MHZ (boot the default frequency is generally between 99-101)

 

Receiving mode: as long as the 88-108MHz FM FM radio can receive, with FM function phone can be.

 

Frequency adjustment mode: adjustable capacitance

 

Output impedance: 50 Ω

 

Scope: high sensitivity wireless microphone, wireless recording, wireless monitoring, maternal and child care, patient care and so on.

 

 

 

This module is the latest micro-chip FM transmitter module, the use of better PCB production process, small size, easy to load rough pen, lighters and so on. The frequency of the module is quite stable and can be used to receive any radio, especially with a digital radio, which works better. All components use branded devices

 

Module supply voltage at 3V, the launch distance in the open environment is about 100 meters, the general indoor environment distance of 20 meters, the higher the voltage the greater the distance, 9V voltage transmission distance of up to 300 meters, the antenna can The use of ordinary wire antenna length of 75 cm or so, must be straightened after use, the test using the best effect of rod antenna!
