Summary

This video tutorial demonstrates how to adjust a sensor-controlled fan system with two trimpots for detection distance and delay. It explains the jumper settings for high and low modes, affecting the fan's operation duration based on movement detection. The video also shows the initial setup, power connection, and how to modify the delay for extended fan operation. Viewers learn to customize the system's response time and can adapt it to control other 12V DC loads like LED lamps.

Takeaways

• 🔍 The sensor activates the fan upon detecting movement.
• 🎚️ There are two trimpots for adjusting detection distance and fan delay time.
• ➡️ Turning the detection trimpot right increases the distance to about 5-6 meters.
• ⬅️ Turning the detection trimpot left decreases the detection distance.
• ⏱️ The delay trimpot controls how long the fan runs after movement is detected.
• ⏩ Turning the delay trimpot right extends the fan's running time to a few minutes.
• ⏪ Turning the delay trimpot left shortens the fan's running time to a few seconds.
• 🔩 Two jumper modes, H (High) and L (Low), determine fan operation based on sensor input.
• 🔻 In LOW mode, the fan turns off after a preset interval regardless of movement.
• 🔺 In HIGH mode, the fan continues to run as long as movement is detected.
• 🔌 The device operates on 12V DC power with red indicating positive and black negative.
• 💡 The fan can be replaced with another 12V load, such as an LED lamp, for different applications.

Q & A

What triggers the fan to turn on in the described system?

The fan turns on when the sensor detects movement.

How can the detection distance of the sensor be adjusted?

The detection distance can be adjusted by turning the trimpot to the right for a further distance (about 5 to 6 meters) or to the left for a closer distance.

What is the purpose of the delay trimpot?

The delay trimpot is used to regulate the length of time the fan runs after it is activated by the sensor.

What happens when the delay trimpot is turned to the right?

When the delay trimpot is turned to the right, the fan runs for a longer duration, which could be a few minutes.

What is the effect of turning the delay trimpot to the left?

Turning the delay trimpot to the left results in the fan running for a shorter duration, only a few seconds.

What are the two jumper modes available, and what do they represent?

The two jumper modes are H (High) and L (Low). In Low mode, the fan turns off according to a preset time interval even if movement is detected. In High mode, the fan continues to run as long as movement is detected.

What is the power source requirement for the system described in the script?

The system requires a 12V DC power source, with red indicating the positive terminal and black the negative.

What happens when the power is first connected to the sensor?

Upon the first connection of power, the sensor immediately activates, causing the fan to turn on and then turn off after a few seconds.

How can the duration of the fan running be increased?

The duration of the fan running can be increased by adjusting the delay trimpot to a higher setting.

Is there a maximum position for the delay trimpot, and what happens when it is set to this position?

Yes, there is a maximum position for the delay trimpot. When set to the maximum, the fan will run for a longer duration than with other settings.

Can the fan be replaced with another type of load, and if so, with what example?

Yes, the fan can be replaced with another load, such as a 12-volt LED lamp, as mentioned in the script.
