The \u003cstrong\u003eC100\u003c\/strong\u003e variant has a manufacturer-specified \u003cstrong\u003e0.25–10 m measurement range\u003c\/strong\u003e, \u003cstrong\u003e1 mm resolution\u003c\/strong\u003e, and accuracy of \u003cstrong\u003e±(1 + 0.3% × S) cm, S = distance\u003c\/strong\u003e, as written in the Milesight datasheet. Unlike the W-series models, this C100 specification does not use a ±1% full-scale accuracy figure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eC100 physical specifications:\u003c\/strong\u003e \u003cstrong\u003eIP67\u003c\/strong\u003e enclosure, black-grey ABS + PC housing, operating temperature \u003cstrong\u003e−15°C to +60°C\u003c\/strong\u003e, relative humidity \u003cstrong\u003e0–80% non-condensing\u003c\/strong\u003e, dimensions \u003cstrong\u003e156.1 × 71 × 69.5 mm\u003c\/strong\u003e, and approximate weight \u003cstrong\u003e362.7 g including the battery and mounting bracket\u003c\/strong\u003e. Supported installation methods are pole, wall or DIN-rail mounting. Leave at least 0.25 m to the measured target and consult the manufacturer’s \u003cstrong\u003eC100-specific ultrasonic beam pattern\u003c\/strong\u003e to assess site suitability.\u003c\/p\u003e\n\u003cp\u003eThe sensor communicates using \u003cstrong\u003eLoRaWAN® OTAA\/ABP Class A\u003c\/strong\u003e and \u003cstrong\u003eMilesight D2D\u003c\/strong\u003e via an internal antenna. NFC mobile-app configuration, local USB Type-C PC software\/console configuration, and remote parameter changes by LoRaWAN downlink are supported. The EM500-UDL can retain \u003cstrong\u003e1,000 local readings\u003c\/strong\u003e and supports data retransmission, retrieval, threshold alerts and change alarms.
