1. Getting Started

The crucial safety measures for module usage, focusing on proper power supply connection, dip switch settings, and pressing frequency to prevent chip damage.

2. Receiver Configuration Guide

This guide provides detailed instructions on configuring the DFRobot Gravity digital wireless switch receiver, including mode switching and pairing techniques, helping users optimize their receiver setup for varied applications.

3. Usage Example for Arduino - Wireless Signal Reception and Pairing

Reference

This article delves into two switch modes for signal transmission: 'press, store energy, bounce, transmit' with energy storage and 'press, transmit, bounce, transmit', highlighting their workflows and impact on signal emission.

Parameter	Value
Working Frequency	433Mhz
Transmission Rate	10kbps
Encoding Format	EV1527
Output Power	13dBm
Modulation Method	OOK
Power Generation Energy	600uJ
Module Size	47x25x11mm(LWH)/1.85x0.98x0.43”
Press Down Force	Typical 1800g
Action Method	Automatically rebound after pressing down
Action Distance	2.6mm (end point)
Press Frequency	no more than 3 times per second, long-term rapid press will cause energy accumulation and cannot be consumed in time, and eventually burn the chip
Stable Transmission Distance	Indoor 40M - Distance Test Condition: Straighten the wire antenna of the transmitting module, and for the receiving module, use Gravity: Digital wireless switch receiver(433MHz)

Name	Function
1. DC input terminal	The DC power input terminal, 3.3V-5V, can transmit signals directly after being connected to the DC power supply. Used to pair with the receiver;
2. DIP switch	Key value selection, dial up to select, from right to left is D0~D3, One must be dialed up when using
3. Power Push Button	Generate energy when pressed
