Construction sites present extreme challenges for PIR sensors: dust, vibration, temperature swings, and no power. This guide covers the best options for equipment security and site monitoring.<\/p>\n
IP65 or higher rating for dust and water. Impact-resistant housing.<\/p>\n
Wireless sensors should last 1-2 years on battery. Solar options preferred.<\/p>\n
Cellular (4G\/5G), LoRa, or long-range wireless for remote sites.<\/p>\n
Sensors must detect if moved or disabled.<\/p>\n
-20\u00b0C to +60\u00b0C typical for construction sites.<\/p>\n
