Product Overview
Low power wireless ultraviolet Sensor is a type of device launched by Shanghai DAQ-IoT Network Technology Co., Ltd., specifically designed to detect and quantify ultraviolet radiation in different bands. Its core function is to achieve precise perception, monitoring, and data output of ultraviolet radiation, and it is widely used in various fields such as industry, healthcare, environmental monitoring, and consumer electronics.
Sensor The terminal supports the use of 4G/LoRa/WiFi communication method, powered by 3.6V lithium battery, overcomes wireless communication obstruction caused by special on-site environment, greatly simplifies on-site deployment time and reduces construction costs. This terminal can also support 12V voltage input, reverse connection protection, high measurement accuracy, and easy installation.
| model | Feature Description |
| --- | --- |
| DAQ-LP-UVLoRaDAQ-LP-UV4G | LoRa/4G communication, powered by long-life lithium batteries, suitable for situations with low acquisition frequency and difficult external power supply. |
| DAQ-GP-UV4G | 4G communication, 220V AC/12V DC power supply, suitable for situations with high acquisition frequency or convenient external power supply. Because the device is set to be online for a long time by default, it can support remote configuration parameter debugging, and only needs to be installed and powered on on-site. |

Product Features
UV Sensor collection characteristics
Collection type: It can simultaneously collect the ultraviolet radiation intensity in the UVA (315-400nm) and UVC (200-280nm) bands, as well as the effective radiation intensity in specific bands of the ultraviolet lamp
Measurement range: UVA: 0-20000 μ W/cm ²; UVC：0~10000μW/cm²； UV lamp intensity: 0~50000 μ W/cm ²
Distance coefficient: For UV lamp monitoring scenarios, the distance coefficient is*1:10*(That is, for every 10 times increase in distance betweenSensorand the UV lamp, the theoretical attenuation of radiation intensity is 1/100 of the original. The device has a built-in distance compensation algorithm that can automatically correct the measurement value based on the actual installation distance.); Environmental UV monitoring scenarios have no fixed distance coefficient and support custom distance calibration
Measurement error: Under standard conditions (25 ℃, 50% RH, standard UV light source), the measurement error is ≤± 5% (@ 20%~80% range of full scale); Band cross interference error ≤± 2%; Long term drift error ≤ ± 3%/year; Additional error ≤ ± 2% in low temperature (-40 ℃) or high temperature (85 ℃) environments
Collection frequency: default once every 12 hours, supports remote configuration
