Purpose. The device is designed for long-term measurement and recording of temperature indications and air humidity, as well as dew point for a certain long period of time in autonomous operation conditions.
Technical properties. The Internet temperature recorder operates in a wide range of operating temperatures from -55 to +125 °C. The error does not exceed 0.5 °C in the range: -10 to +85 °C. Based on humidity and temperature readings, it indicates the dew point.
Scope. It can be used in the storage and transportation of food, medicines, and chemicals.
Advantages. Low cost of components, ease of maintenance and installation. Some software libraries used for data visualization are open source. The software developed for the server part is easily installed on most operating systems.
Description. Using the WEB interface, you can set temperature and humidity limit values, upon reaching which the recorder will signal an alarm using light indication or a notification in a special telegram channel. The obtained measurement results can be stored in Excel format. The data is sent to a special server via a Wi-Fi module, where, using a developed web application, it is visualized and stored in a database.
