HC-SR501 Motion Detector Module Passive Infrared PIR Sensor

The DHT11 humidity sensor is presented in a plastic body ideal for mounting on a panel or similar. It uses a capacitive sensor that returns a digital signal with the measurement.
Characteristic:
- Operating voltage: 3 to 5 VDC - Humidity measurement range: 20-95% ± 5% accuracy
- Temperature measurement range: 0ºC to 50ºC ± 2º accuracy
- Maximum sampling rate: 2 seconds - Working current 2.5mA
- 1-wire interface
- Dimensions: 32 x14 mm
- Quantity: 1 unit with 3x female / female cables

Protective cover used for micro: bit. The cover has two different sides, dot matrix display area, finger usage area on the front. Micro USB interface, power interface and reset button on the back side. It can be installed on a micro: bit board to make your work more charming and fun. Weight: 10g
Size: 5.5cm * 6.5cm
Material: silica gel (environmental protection material)

The module is based on a touch sensitive IC capacitive touch switch module (TTP223B).
In the normal state, the module produces Low power consumption. When a finger touches the corresponding position, the module output is high, if not touched for 12 seconds, it switches to low power mode. Digital Touch Sensor B21 features:
- Low power consumption
- Input voltage: 2 - 5.5VDC
- Can replace the traditional touch of a button - Four M2 screws diameter 2.2 mm that position the holes for easy installation
- 3-pin control interface:
1- GND
2- VCC
3- Control signal (output pin)
- Power indicators: Bright green LED when the sensor is on
