Product Description:

YJJ 24G Breathing Feature Is Equipped With A Millimeter-Wave Ranging Radar Sensing Module

Features:

Parameters of the 2.4GHz wireless module fall into two main types:

Industrial-grade G24 module (GSM/GPRS)

‌Communication standard: Supports four-band GSM/GPRS/EDGE (850/900/1800/1900 MHz)

‌Physical size: 24.4×45.2×6.0mm (miniaturized design)

‌Operating voltage: 3.3 - 4.2V

‌Environmental adaptability: Standard version -20°C to +60°C, Extended temperature version -30°C to +85°C

‌Interface type: 70-pin socket, UART, USB

‌Data transmission: GPRS Class 10 (downlink rate up to 85.6 kbps), supports 5 concurrent channels 1

Wireless transmission module (2.4GHz ISM band)

‌Operating frequency‌: 2.4 - 2.525GHz

‌Transmission power‌: Up to 27dBm (typical application scenarios)

‌Test distance‌: 4 kilometers (open environment)

‌Package size‌: 18 × 14.5mm (surface mount model)

‌Power consumption‌: Standby current 15μA, transmission current approximately 17mA 2

The application scenarios of these two types of modules are quite different. The industrial-grade G24 module focuses on cellular network communication, while the data transmission module is more suitable for short-distance high-speed data transmission.

This module is mainly used in the field of industrial Internet of Things. Typical cases include:

Remote meter reading system: Realizes the transmission of smart meter data through the GPRS network

Vehicle monitoring terminal: Integrates a GPS module, supports GPRS network data transmission, suitable for vehicle positioning tracking and other M2M scenarios

Smart home control: Connects to the ARM main control chip through the RS232 interface to achieve remote start/stop of air conditioners and video monitoring [2]

Power equipment monitoring: In the remote wireless meter reading control device, forms a hybrid communication network with ZigBee networking
