Here is a simple optoreflective sensor circuit based on TCRT5000 module. It is ideal for projects like robotics, position sensing, proximity sensing, detection of reflective materials and many more.

In this tutorial we discussed the Sound sensor, its pinout, working, and how to interface it with Arduino. This article includes a complete Arduino code and circuit diagram along with a step-by-step ...

Circuit Diagram for IR Motion Sensor Module The schematic diagram of the IR Motion sensor is shown below. The schematic itself is very simple and needs a handful of generic components to build. If you ...

Here is the basic circuit diagram of the UV Sensor Module, drawn & checked by me (thanks to my USB microscope and LCR meter).In the circuit PD1 is the GUVA-S12SD, and U1 is the SGM8521. The only one ...

The purpose of this circuit is to animate shop-windows by means of a capacitive sensor placed behind a post-card-like banner. The card is placed against the glass inside the shop-window, and the ...

Set up for microcontroller designs This is the proposed wiring diagram for the ‘hacked’ sensor box. Now the shock/vibration sensor is ready to work with any microcontroller – no matter how it’s ...

This Module employs an unusual topology, still maintaining the basic op-amp circuitry of the Main Module with a few changes in resistor values. A special feature of this circuit is the use of six ways ...

Replacement Trion 348818-001 Power Supply (with integrated air flow sensor) The components shown in the bottom right corner of the PCB implement the air flow sensor module. These are the same ...

The circuit diagram of the infrared sensor based power saver is shown in Fig. 2. It is built around bridge rectifier DB107 (BR1), PIR motion sensor connected across connector CON2, timer NE555 (IC1), ...

Can you buy a working radar module for $12? As it turns out, you can. But can you make it output useful information? According to [Mathieu], the answer is also yes, but only if you ignore the datas… ...

The BMP180 module is connected to the Arduino's A4 and A5 pins. Arduino-HCSR04 Module Connection Diagram: The HCSR04 module is connected to the Arduino's trig pin (D8) and echo pin (D9).
