This mini doppler radar sensor module is equipped with supporting DC 4-28V wide voltage This is a mini radar motion sensor module is equipped with RCWL-9196 chip based on the doppler microwave induction technology. It will automatically comtinuously output the high level TTL signel when there is motion. 360 degree no blind angle detection and maximum 7m sensoring distance with adjustable delay time and sensitivity. It is perfect for DIY microwave motion sensor light switch, human sensor toys, smart security devices, etc.

Notice:

Overview

• Detects shake signal
• Signal output indicator

Specifications

How to Use

In the case of working with a MCU:

• VCC ↔ 3.0V ~ 5.5V
• GND ↔ power supply ground
• DOUT ↔ MCU.IO (digital output)

A vibration switch, also called spring switch or shock sensor, is an electronic switch which induces shock force and transfers the result to a circuit device thus triggering it to work. It contains the following parts: conductive vibration spring, switch body, trigger pin, and packaging agent.

Features
1. A low-power touch switch module of jog type.
2. Keep the current on/off state and only change it till the next touch.
3. Working voltage: 3.3 - 5V.
4. With power light and signal output indicator.
5. PCB size: 2.0 x 2.0 cm.
 

Features
1. A reed switch module to detect the magnetic field. Different from Hall sensors which are generally used to measure the speed of intelligent vehicles and count assembly lines, reed switches are often used to detect whether there is a magnetic field.
2. Use a normally open reed switch.
3. Working voltage: 3.3-5V; PCB size: 2.0 x 2.0 cm.
4. Output digital signals.
5. With power light; a 3-pin anti-reverse cable included.

Features
1. USAGE - A tilt switch is to detect an inclination.
2. BIDIRECTIONAL CONDUCTION - Use a ball switch as bidirectional conduction.
3. ANTI-REVERSE PORT - Provides a firm connection.
4. INDICATORS - With an indicator for digital signal output. 
5. Working voltage: 3.3-5V; PCB size: 2.0 x 2.0 cm

Features
1. An infrared tracking sensor module that uses a TRT5000 sensor. The blue LED of TRT5000 is the emission tube and after electrified it emits infrared light invisible to human eye. The black part of the sensor is for receiving; the resistance of the resistor inside changes with the infrared light received.
2. The sensor TRT5000 is highly sensitive with reliable performance.
3. Utilize infrared to detect, high capacity of resisting disturbance.
4. Working voltage: 3-5V DC; PCB size: 1.4 x 3.5 cm.
