That’s because a motion sensor is like a light switch that is naturally in the ‘off’ position. That wouldn’t work if you wanted multiple motion sensors on one circuit. This is called a series circuit – where the current travels from the power source through each component. To be clear, daisy-chaining motion sensors would be where you put them on the same circuit in a single loop. What matters is how they’re wired up, so let’s look into that more. In theory, you can have as many sensors as you want on a circuit, which could be good for outdoor lights if you want to cover more than two directions and you have an expansive garden. Using your outdoor lights to deter potential intruders, you’ll have more coverage without needing to double-up on lights – just multiple sensors. Outside, you may prefer to wire all your lights to motion sensors covering the front and rear of your home. It is possible to wire two motion sensors to the same light, provided you wire them correctly.įor indoor sensors, you might want the staircase lighting attached to a motion sensor at the top and bottom of the stairs so that the lights switch on when you’re approaching them from either floor. How to wire multiple motion sensors on one circuitĬan I Have Two Motion Sensors To The Same Light?.Why you can’t daisy-chain motion sensors.Whether it’s possible to have two motion sensors working on the same light. To explain in a bit more detail, let’s take a look at: You can wire the sensors to the light separately in a parallel circuit, and they will work independently. You can wire two motion sensors to the same light, but not in series otherwise, both would need to be triggered for the light to work. You can’t cover everything with one sensor, but can you wire one light (or set of lights) to two sensors? Otherwise, they would be triggering all the time.īut what if you have one light that you want to be activated depending on whether there’s movement in different places? They are designed to cover a specific area that you have them pointed at. Motion sensors are not omnipresent – they can’t be all-seeing because they are, to an extent, directional.
