The source states an operating frequency of 10.525 GHz and lists security systems, automatic doors and speed measurement among possible applications.<\/p>\n<h4>Specifications stated by the source<\/h4>\n<ul>\n<li>Operating frequency: 10.525 GHz<\/li>\n<li>Supply: 5 V DC<\/li>\n<li>Typical current: 40 mA<\/li>\n<li>Maximum detection distance: 20 m (source-listed)<\/li>\n<li>Output: analog IF signal<\/li>\n<li>Detection angle: 15\u00b0<\/li>\n<li>Dimensions: 46 \u00d7 40 \u00d7 11 mm<\/li>\n<li>Weight: 8 g<\/li>\n<li>Price: MAD 80<\/li>\n<\/ul>\n<p>The sensor detects Doppler frequency changes in reflected microwaves. The source says its analog output may be amplified and processed to estimate speed. Its 20 m range and 15\u00b0 angle are listing claims and depend on setup and conditions.<\/p>\n<h4>Arduino Uno wiring listed<\/h4>\n<p>Parts: HB100 module, Arduino Uno, jumper wires and breadboard; a signal amplifier may be needed. Connect VCC to 5 V, GND to GND and IF to analog input A0.<\/p>\n<h4>Source example 1: serial output<\/h4>\n<pre class=\"prism undefined-numbers lang-cpp\" data-lang=\"C++\"><code>const int sensorPin = A0; \/\/ Broche connect\u00e9e \u00e0 la sortie du capteur\r\nvoid setup() {\r\n\u00a0 Serial.begin(9600);\r\n}\r\n\r\n\r\nvoid loop() {\r\n\u00a0 int sensorValue = analogRead(sensorPin);\r\n\u00a0 float frequency = sensorValue * (5.0 \/ 1023.0);\r\n\u00a0 float speed = frequency \/ 31.36; \/\/ Conversion de la fr\u00e9quence en vitesse en mph\r\n\u00a0 Serial.print(\"Vitesse: \");\r\n\u00a0 Serial.print(speed);\r\n\u00a0 Serial.println(\" mph\");\r\n\u00a0 delay(500);\r\n}<\/code><\/pre>\n<p><strong>Important:<\/strong> the source example converts an analogRead value into a frequency and then speed using a fixed factor. This is not a validated measurement method for the HB100 as listed. Use a suitable IF amplifier and a verified frequency-measurement and calibration method before relying on speed values.<\/p>\n<h4>Source example 2: 1602 I\u00b2C LCD<\/h4>\n<p>Parts listed: HB100, Arduino Uno, 1602 I\u00b2C LCD, jumper wires and breadboard; an amplifier may be needed.
