Do you mean an IR (PIR) motion sensor kit to automatically switch a 240 V AC light on/off? 🤔
If so, here’s a clear overview and options—then I’ll ask one quick clarifying question.

What you’re likely referring to

Most “IR sensor kits” for lights are actually PIR (Passive Infrared) motion sensors, commonly used for:
Security lights
Automatic corridor / outdoor lights
Energy saving (light turns on only when motion is detected)
They detect body heat movement, not reflected IR like remote controls.
Common options for 240 V AC lights

1️⃣ Direct 240 V PIR sensor (recommended)

Designed to work directly on 220–240 V AC
Has built-in relay to switch the light
Adjustable:
Time delay (how long the light stays ON)
Sensitivity
Day/Night (LUX control)

✅ Safest & simplest
❌ Limited customization

2️⃣ Low-voltage IR/PIR sensor + relay module

Sensor works at 5 V / 12 V DC
Relay module switches the 240 V AC light
Often used in DIY / Arduino projects

✅ More flexible

⚠️ Requires proper electrical knowledge and

isolation
3️⃣ Smart PIR switch
Replaces wall switch
Built-in PIR + manual override
Some support Wi-Fi / Zigbee

✅ Clean installation
❌ More expensive

⚠️ Safety note (important)

240 V AC is dangerous. If you:
Don’t have experience with mains wiring
Don’t have proper insulation, enclosure, and earthing
👉 Use a certified 240 V PIR sensor or get an electrician.

Quick question to narrow it down

Do you want this for: 1️⃣ Direct mains use (no microcontroller)
2️⃣ Arduino / DIY electronics project
3️⃣ Indoor or outdoor light
Tell me that, and I can suggest the exact type of sensor/module you should use 👍
