Specifications:
Model: JDY-41
Color: Green
Working frequency band: 2.4G
Transmission power: 12 db
Working temperature: -40℃ to 80℃
Reception sensitivity: -96 db
Transmission distance: 160 meters
Working voltage: 2.2V-3.6V
TX current: 40mA
RX current: 24mA
Sleep current: 10uA
Communication interface: Standard TTL serial port

Features:
1. 2.4G long-range transparent transmission; up to 160 m line-of-sight; each packet uses a checksum to avoid garbled data.
2. UART supports transparent and command modes with target addressing and ACK confirmation, so the sender can know if data was received.
3. Serial commands can drive receiver GPIO pins to high or low levels for switch control.
4. Learning remote mode: the receiver learns the transmitter’s ID and then accepts only that controller; supports low-power remote use.
5. PCB package compatible with JDY-40, but the communication protocol is completely different.

Package included:
1 x JDY-41 Module
or
1 x Antenna

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
