KR-M623
一. Product Introduction
This power generation module utilizes the principle of electromagnetic induction power
generation. It generates a pulse current each time the pressing action, driving the transmitter to
work once, and cooperates with the independent running OOK emission IC with encoder,
without external MCU control, to achieve single chip, high-flexibility wireless communication.
Functionality, this transmitter replaces the traditional battery, eliminating the cost of late
replacement of the battery, energy saving and environmental protection.
二, the main indicators
1. Power generation module word power generation (press and rebound) >600uJ
2, action intensity: about 1650g
3, service life: >100,000 times
4, operating frequency: 433.92MHZ
5, the use of the environment: -20 °C ~ 40 °C
三, the operation instructions
The transmitter power generation module adopts full-bridge rectification. When it is pressed, it
stores energy. When it pops up, it drives the back-end circuit to work. The stroke is 2.6mm.
When you press it, you hear a “click” and it means press; release your finger and it will pop up.
"One click, indicating that a job has been completed and the transmitter has transmitted a
signal.
四, match with the doorbell host
Hold down the doorbell host [] key 5s, the host "drip" a sound, indicating that entering the
pairing state, trigger the transmitter, the host "drip" two, once again trigger the doorbell button,
the host "drip" indicates a successful match; by host Press any key to exit the learning state
五. Precautions
The minimum pressing pressure for normal operation of generator keys is about 1450g to
ensure the normal operation of the generator.
