This Solar Powered Animal Scarer Circuit is small and simple to give a try for.
It uses solar panel to take power from sun.
At night or at low light the battery gives power.
Circuit make sound or light to scare animal like dog, cat, monkey or birds.
So they do not come near farm, garden or home.
It work automatic with no need to always switch ON.
Circuit Working of Animal Repellent :
Parts List:
| Category | Part Description | Quantity |
|---|---|---|
| Resistors | 100Ω 1/4 watt | 3 |
| 1M 1/4 watt | 1 | |
| Potentiometer 100k | 2 | |
| Capacitors | Ceramic 0.22µF | 1 |
| Semiconductors | IC 4060 | 1 |
| LDR | 1 | |
| LEDs 5mm 20mA | 9 |
This solar circuit scare night animals like bat, cat from farm, garden.
It make bright flash red, blue, white LED.
Works auto with ON at night and OFF at day.
LDR with IC CD 4060 control flashing.
VR1 set light sense and VR2 set flash speed.
The circuit uses 12V battery or supply.
Formulas:
We can use IC 4060 to make animal repeller circuit.
Use this formula to find frequency (approx):
f = 1.44 / ((R + 2 × Rpot) × C)
where,
- Rpot is variable resistor we can turn to change frequency.
To stop LED burning use resistor:
RLED = (Vsupply – VLED) / ILED
where,
- Vsupply is the battery power
- VLED is LED voltage for 2V
- ILED is LED current from 10 to 20 mA
How to Build:
To build a Solar Powered Animal Scarer Circuit one needs to follow the below mentioned steps:
- Gather all the part as per circuit diagram LDR goes to pin 12 of IC 4060 for reset by light.
- VR1 with LDR set sensitivity.
- VR2 set LED flash speed.
- R1, R2 with VR2 limits the LED current.
- Use diode 1N4007 with panel and battery to stop reverse power.
Connect LEDs like this:
- Red to pin 7
- Blue to pin 5
- White to pin 4

Parts List:
| Category | Part Description | Quantity |
|---|---|---|
| Resistors | R1 10Ω 1 watt | 1 |
| R2 1k 1/4 watt | 1 | |
| Capacitors | Electrolytic 2200µF 12V | 1 |
| Semiconductors | Diodes 1N4007 | 2 |
| LED any 5mm 20mA | 1 | |
| Solar Panel 18V | 1 | |
| Battery 12V | 1 |
This circuit take power from solar battery.
Day time battery charges by sun with R1, D1 and green LED show charging.
Night time D1 stop and D2 give battery power to circuit.
R1 limits the current and big C1 keep power smooth.
How to Build:
Below mentioned are the steps to build a Animal Scarer Solar Power Supply Circuit:
- Solar positive goes to battery positive.
- Solar negative goes to D1 anode.
- D1 cathode goes to battery positive and LED anode.
- LED cathode goes to battery negative.
- D2 cathode goes to battery negative.
- D2 anode goes to circuit positive.
- R1 one side goes to solar positive and other side to D1 anode.
- C1 positive goes to D1 anode and C1 negative goes to battery negative
Conclusion:
This Solar Powered Animal Scarer Circuit is good to stop animals.
It does not hurt animals but it uses light, sound or special waves to scare them.
