HG803 Series Temperature and Humidity Monitor has been designed to measure, monitor and record temperature and humidity.
It is a perfect solution for any facilities where monitoring and recording such values are very important for the accuracy of the
whole process e.g.: in server rooms, drug and food warehouses, laboratories, museums or glasshouses.
The data captured by HG803 is stored in the internal memory and then sent digitally to the user (by the Ethernet).
Using the Internet of Things technology can realize the data collection, processing, transmission functions,
can realize the dynamic and real-time monitoring of the data.

Humidity values in glasshouses are important indicators of good plant growth. Or to avoid plant diseases. High air humidity can stimulate the growth of harmful fungi, promote other diseases or impair the nutrient uptake of plants. The relative humidity should ideally lie in a range of 50 – 85 %RH.
The measurement and monitoring of relative humidity make it possible to control humidification and fogging systems. They come into action when the humidity is too low. If the humidity is too high, a ventilation or heating system can help. In all cases, the use of these systems should be controlled optimally to keep energy costs down.
The measurement and monitoring of relative humidity are just as important in feed drying and storage as it is in big-bale technology and seed storage.

FURTHER APPLICATIONS
Environmental chambers
The effects of simulated and accelerated environmental changes on plants are investigated in special climate chambers. Instruments to measure humidity, temperature and CO2 are used in these chambers.
Seed research
One focus in seed storage and research is the measurement of water activity.
