Buy & Import GUVA-T21GH UV Sensor Module from Week Technology Ltd. - Wholesale Supply

The GUVA‑T21GH UV Sensor Module is a compact component that detects ultraviolet radiation using a silicon photodiode paired with a UV‑responsive epoxy lens. It operates from a single supply voltage and delivers an analog voltage proportional to the intensity of UVA and UVB light. The module is sized for space‑constrained designs and integrates readily with microcontroller platforms such as Arduino and ESP32. Week Technology Ltd. supplies the device from its facility in Shenzhen, China.

Silicon photodiodes are the standard active element in UV sensors because of their stability and linear response across the 260‑400 nm range. Typical UV sensor modules employ an epoxy‑capped lens to filter visible light and enhance solar blindness, matching the construction of the GUVA‑T21GH. In the industry, analog output modules commonly operate between 3.3 V and 5 V and achieve response times under one second, which aligns with the performance of this unit. Buyers often receive the sensors in bulk reels or trays, a packaging format that facilitates automated assembly lines.

The module is suited for portable UV monitoring devices, wearable sun‑exposure trackers, environmental monitoring stations, and industrial UV‑curing equipment. Importers typically order the parts in bulk quantities, and Week Technology Ltd. states that flexible minimum order quantities are available, though exact figures should be confirmed directly. Shipping can be arranged on FOB or CIF terms, allowing buyers to select the most appropriate logistics arrangement for their supply chain. Prospective buyers are advised to verify any required certifications and request sample units before committing to large‑scale production runs.
