Ruggedized Arduino PIR Motion Detector – Waterproof / Corrosion Resistant Motion Detect Sensor


This rugged PIR motion detector moisture is the most cost-effective lifetime solution for hidden sentry motion detection where the sensor may be placed within potential harsh environments.

Such applications may include hidden areas such a within a plant that frequently receives watering.  The rugged waterproof motion detector is an ideal motion detect sensor for any Arduino, Raspberry Pi, ESP8266, microcontroller or IoT project application.



This ruggedized PIR motion detector sensor is waterproof, corrosion resistant and industrially protected for optimal durability and sustained performance.  This waterproof motion detector is perfect for hidden motion and discrete sentry applications.

Adosia first applies a dual coating of a waterproof urethane conformal protecting sealant the PCB components. We then further insulate from moisture using a dual walled and glue adhesive-lined waterproofing heat shrink.

Further ruggedizing and waterproofing the motion detect sensor is necessary to ensure long life operation of the motion detector – from Arduino prototypes extending to real world applications.

A rugged and waterproof PIR motion detector increases system reliability while also lowering the total cost of ownership and reducing overall maintenance of your IoT and/or gardening systems. Without ruggedizing and waterproofing, the motion detector sensor circuitry is all but guaranteed to short out when it gets the slightest bit wet.

The ruggedized PIR motion detector sensor works with Arduino, or Raspberry Pi, Adosia IoT systems or any microcontroller capable of reading a 0-3.3V digital input signal.
