1、Greenhouse Accumulated Temperature Meter Product Overview
Greenhouse Accumulated Temperature Meter can measure two parameters: accumulated temperature and accumulated light. It can record temperature, humidity, air pressure, light intensity, CO2, photosynthesis, active accumulated temperature, effective accumulated temperature, and accumulated light around the clock.The JWG series Greenhouse Accumulated Temperature Meter utilizes a high-precision sensor module to monitor key environmental parameters in real time, including air temperature and humidity, atmospheric pressure, light intensity, photosynthetically active radiation, accumulated temperature, effective accumulated temperature, and accumulated light intensity. Monitoring data is wirelessly transmitted to a cloud platform via low-power IoT technology, allowing users to view real-time data and historical trend curves anytime through a client application. The device features a built-in lithium battery, solar charging, and an intelligent sleep algorithm, meeting the needs of long-term unattended monitoring. Its waterproof casing design allows it to adapt to complex agricultural environments such as rain, snow, high temperatures, and high humidity under appropriate installation conditions. No installation is required; simply press the switch to operate.
Greenhouse Accumulated Temperature Meter provides precise environmental data support for agricultural production, helping growers scientifically regulate temperature, light, water, and fertilizer, optimize crop growth environments, reduce disaster risks, and improve agricultural production efficiency and product quality. It is particularly suitable for greenhouse agriculture, facility agriculture, field planting, smart agricultural parks, and seed breeding bases.
