URI Indoor Relative Humidity Sensor
- Manufacturer: Nesa
- Category: Meteorology – Climatology, SENSORS, Humidity Sensors, Temperature sensors, Temperature sensors for air conditioning, Temperature - Humidity
The NESA URI is an indoor relative humidity sensor with a thin-film capacitive transducer, a typical measurement range of 0 ÷ 100 %Rh and a plastic body (26 x 220 mm).
It features a resolution of 0.1%, accuracy of ±2% fs, and a response time of less than 90 s (10–80% RH). It is supplied with a calibration report and a 5 m cable in versions with 0–1 Vdc (URI-A), 4–20 mA (URI-B), or RS485/Modbus (URI-C) output.

Technical Frequently Asked Questions
What output signals does the URI indoor humidity sensor provide?
It is available in three versions with a 5m cable: URI-A (0÷1Vdc voltage output), URI-B (4÷20mA current output) and URI-C (RS485/Modbus output).
How do I order the URI indoor relative humidity sensor?
The order code combines the sensor (URI), the output (A, B, or C), and the sensor-datalogger cable (05 = CS05, 5 m; 10 = CS10, 10 m; xx* = CSxx, length in meters to be specified in the order), and the anodized aluminum SSM wall mount for ø25 mm sensors, positioned approximately 12 cm from the wall. Manufacturer example: URI A 10 SSM. Available references are URI-A, URI-B, and URI-C.
Under what environmental conditions does the URI sensor operate?
It operates between -40 and +60 °C with a 10÷30Vdc power supply, consumes less than 0.1 W and weighs less than 80 g.
