UVB Ultraviolet Temperature Humidity Tester Module LCD Display Digital UV Index Meter SHT30 Sensor With CR2032 Battery Holder For Outdoor

UVB Ultraviolet Temperature and Humidity Tester

📌 Product Overview This UVB ultraviolet temperature and humidity tester is a multi‑function detection device equipped with dual high‑precision sensors: SHT40 for temperature‑humidity detection and GUVB‑C21SD for UVB intensity measurement. It is powered by a CR2032 button battery with a service life of about 3‑4 months. The built‑in algorithm automatically completes temperature and humidity calibration without manual adjustment. The e‑ink screen clearly displays real‑time data, and the simple one‑button operation makes measurement convenient. It is widely used for reptile breeding box monitoring, UVB lamp effect testing and environmental parameter inspection. ✨ Core Features

• Dual‑sensor design: SHT40 temperature & humidity sensor + GUVB‑C21SD UVB sensor
• Automatic algorithm calibration for temperature and humidity, no manual operation required
• High measuring accuracy: temperature error ±0.3℃, humidity error ±3% RH
• UVB detection wavelength range: 285‑315nm, accurate ultraviolet intensity reading
• Powered by CR2032 battery, continuous working time reaches 3‑4 months
