AT-09 HM10 4.0 BLE Bluetooth Module In Pakistan

Mounting Bracket Holder Stand is specifically designed for the HC-SR04 Ultrasonic Sensor Module. With this ultrasonic sensor you can attach the le to your application such as small robots or DIY projects very quickly and conveniently. This best mount bracket is made from good quality Acrylic. This mounting holder has mounting holes of a diameter of 3.8mm. Use this Arduino distance measuring sensor to easily attach your ultrasonic distance sensor to your robots, onto a servo for panning, and anywhere else you’d like. 90 degree mounting with 3 screw holes at the base and 4 screw holes for the ultrasonic sensor itself.

The Digital Light Dependent Resistor LDR Sensor Module is used to detect the presence of light / measuring the intensity of light. The output of the LDR module goes high in the presence of light and it becomes low in the absence of light. You can adjust the threshold (sensitivity) of the digital output by tuning the onboard variable resistor (potentiometer). Simple usage as it is the digital output, so you will know is the light present and decide what to do with it.LDR photoresistor sensor module comes with an M3 mounting hole for ease of attaching it to an object. Onboard, it provides an LDR, high sensitivity and commonly being used for light detection.

The PIR Motion Sensor Detector Module HC-SR501 allows you to sense motion. It is almost always used to detect the motion of a human body within the sensor’s range. It is often referred to using “PIR”, “Pyroelectric”, “Passive Infrared” and “IR Motion” sensor. The module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It has a delay time adjustment Potentiometer and sensitivity adjustment Potentiometer. Repeat Trigger Selection solderable Jumper is also available.
