Wie wir bewerten
Unsere KI-gesteuerte Plattform bewertet Produkte anhand mehrerer gewichteter Faktoren aus Millionen von Produkten und Nutzerbewertungen im Web und liefert die wertvollsten und realistischsten Daten. Höhere Bewertungen rangieren zuerst.
*Usage: The OUT output sensor module can be directly connected to the microcontroller port and can directly drive 5V relays.
*Features: The infrared sensor module has a pair of infrared emitting tubes and receiving tubes. The infrared emitting tubes emit at a certain frequency. When the detection direction encounters an obstacle (reflective surface), it will be reflected to the infrared receiving tube. After being processed by the comparator circuit, the green indicator light will light up, and the signal output interface will output a digital signal (low-level signal).
*Distance: The detection distance of the infrared module is 2 to 30 centimeters, the detection angle is 35 degrees, and the distance between the detectable potentials can be adjusted.
Multiple Operating Modes: 1. Night Mode:Turn on light control,It will not be activated during the day but will be activated at night. 2. Daylight Mode: The Light sensor is disabled.It senses whether there is light or not during the day. 3. ON:Keep the device powered on and disable the delay function. 4. OFF:Disable all functions. Sensing Angle: 120°,Inductive distance:8 meters,Recommended installation height: 1.8–2.5 meters. please note the installation method when using.
Motion Sensor Detection:The Clearhill Mini PIR Motion Sensor Switch features strong anti-interference capabilities,Adopting digital serial porttype pyroelectic sensor head, the perfomance is stable and reliable.It automatically detects ambient light levels and adjusts accordingly.Fully automated motion detection turns the light on when people are present and off when they leave, enhancing safety and saving energy.Compatible with 5V/12V/24V DC devices.
Adjustable Delay Timer: It is used to set the time interval between the detection of no human signal by the sensor and the tuming off of the lighting equipment. The delaytime can be adjusted by a button as needed.The adjustable delay range of this product is: 15seconds-30 seconds -60 seconds -120 seconds.
【Pack of 5 Motion Sensors】 – Includes five HC-SR501 PIR motion sensors, providing excellent value for multi-project setups and DIY electronics.
【Adjustable Sensitivity & Delay】 – Customize sensor responsiveness and trigger duration using onboard knobs to suit different environments and needs. Customize the detection range and delay time for optimal performance in various environments.
【Accurate Infrared Detection】 – Senses human motion using passive infrared (PIR) technology with up to 7 meters (23 ft) range and 120° field of view.
※Widely used in music playback, speech recognition, voice communication and other fields, it can improve the sensitivity and sound quality of the audio system
※MAX4466 Sound Sensor: Realize sound detection, analysis and recognition, and effectively amplify and preprocess weak sound signals so that subsequent algorithms can extract and analyze sound features
Wide Voltage Support – Operates on DC 3.3V to 6V, making it compatible with both 5V Arduino boards and 3.3V ESP32/Raspberry Pi systems.
Mixed Package for Flexibility – Includes 4× DHT22 & 4× DHT11, allowing you to choose between high-accuracy (DHT22) or cost-effective (DHT11) options for different applications.
High-Precision Environmental Monitoring – DHT22 provides superior accuracy (±0.5°C temperature, ±2% RH humidity), making it ideal for critical projects like smart agriculture, HVAC systems, and lab monitoring.
