What would house an LDR
To answer your question, an LDR (Light Dependent Resistor) is typically housed in a simple circuit setup along with other electronic components. The purpose of the housing is to protect the LDR from any physical damage and provide a stable environment for accurate light detection.
Here are the steps to set up a simple circuit to house an LDR:
1. Gather the components: You will need an LDR, a resistor (usually in the range of 10k to 100k ohms), a breadboard, connecting wires, and a power source (such as a battery or power supply).
2. Connect the LDR to the circuit: Insert the LDR into the breadboard, connecting one leg of the LDR to the positive rail of the breadboard, and the other leg to one end of the resistor. Connect the other end of the resistor to the negative rail of the breadboard.
3. Connect the power source: Depending on the voltage requirements of your LDR, connect the positive terminal of the power source to the positive rail of the breadboard and the negative terminal to the negative rail of the breadboard.
4. Measurement circuit (optional): If you want to measure the resistance change of the LDR based on light intensity, you can connect a voltmeter or an Arduino to read the voltage difference across the LDR and the resistor. This will allow you to monitor the light levels detected by the LDR.
5. Housing the circuit: To protect the LDR and other electronic components, you can use an enclosure such as a plastic project box or a custom-designed case. Make sure the housing provides enough space for the circuit and allows access to the LDR for light detection.
Remember to take necessary precautions when handling electronic components and ensure the circuit is properly secured within the housing to prevent any accidental damage or electrical hazards.
