AIHJCNELE RCWL-0516 Microwave Radar Sensor Switch Module Human Body Sensing Board Intelligent Induction Detector Motion Detection 5-7M for Arduino ESP8266 Nodemcu Better Than HC-SR501 (RCWL0516 6pcs)
R60ABD1 radar module is the use of 60G millimeter wave radar technology, detection of human skin subtle changes, through the algorithm to calculate the respiratory frequency, heartbeat frequency, motion amplitude, abnormal activity information.
Secondary development information: 1) Radar built-in algorithm processor, direct output results, no need for cloud computing 2) The detection results of radar are output by SCM serial protocol 3) Communication module (WiFi, 4G, etc.) is not included in the design of radar module.
Detection range: 1) Trigger range and accurate detection range of yunfan radar calibration 2) The maximum accurate detection range is usually within 40 degrees conical Angle within the design range of radar antenna.
3) The radar detection range can be adjusted by adjusting the Angle and distance 4) The detection accuracy is closely related to the detection target distance.
Usage: 1) Installed in a fixed position, accurate detection of external moving objects 2) Radar penetrates low density objects such as thin wooden planks. Caution False positives are caused by large detection range 3) Due to different electromagnetic wave noise in different environments, electromagnetic environment at the bottom of radar is required in some cases.
Treedix USB to TTL Converter CH340 Module 3.3V/5.5v Serial Converter Development Tool with Micro USB Adapter for Arduino
Serial Basic Breakout Board CH340G serial signal serial ic breakout development board usb micro b connector save space diy electronics projects micro b cable jumper wires.
Base on USB converter IC CH340G, there is a wide range of operating systems . You may need to install drivers the first time you connect the chip to your computer's USB port or when there are operating system updates..
The output voltage is 3.3v by default, there is a 3.3v signal, it can also be changed to 5V, changing to 5V will cause the board to output 5V and 5V signals on the VCC pin(3 .3v to 5V by a short circuit selection).
There are two LEDs on the board connected to TX (green) and RX (yellow) for faster viewing of serial traffic.
Suitable for: Arduino Pro Mini, our GPS module, cellular module and many other devices that use serial communication.
