Heavy duty IP66 ready, working till -40°. Sensor housing is manufactured in Germany by BOPLA. The sensor can be washed. The latest digital sensors from Sensirion.
Up to 10 years of work
Basic transmission schedule - every 10 minutes. In cold conditions capacity of the battery is reduced, but the sensor will still work for more than 8 years.
Money saving
The sensor is fully maintenance-free and saves you money right from the start
3 years warranty
We will replace the device with a new one without any questions, if something happens with him
Easy to mount
No wires required, anyone can do it. No settings are required, just turn it on. The sensor battery is replaceable.
Reliable and long-range radio channel

Experience with sensors
Look at different device use cases
We cooperate with Cherkizovo Group of Companies. In fact, the sensor was created in the interests of logistics and poultry farming departments. Our monitoring network covers 52 regions of Russia, more than 1000 sites. Air temperature and humidity are very important for the health and proper growth of the bird. High dust content and the presence of manure make the operating conditions in poultry houses extreme. After each grow cycle, the sensors are disinfected with strong chemicals and washed under high pressure. Long-term operation of the sensor has confirmed tightness, resistance to dust and active chemicals.
All sensors are in a single network. This allows you to monitor in one console the sites on which a wide variety of industrial automation equipment is installed. Cherkizovo Group independently integrated the SAP R3 accounting system with our cloud. According to Cherkizovo Group of Companies, the use of the system made it possible to reduce the cost of production by 2% and 10% of maintenance costs.

Monitoring of air quality and parameters of temperature and humidity in offices and server rooms of Otkritie Bank. Monitoring temperature and air humidity is very important to ensure a comfortable working environment. The climate directly affects the performance and health of employees and office visitors. Wireless sensors are easy and quick to install. Battery operated, no wiring required. A beautiful case does not spoil the interior. Autonomous sensors in server rooms allow you to monitor the situation even in the absence of power supply.
The air terminal complex of Sheremetyevo International Airport has implemented a temperature monitoring system based on GoodWAN equipment and wireless technology. The monitoring system allows to increase the level of control over the temperature regime in the air terminal complex, which ensures the comfort of passengers, as well as the uninterrupted operation of technological equipment.
Sheremetyevo International Airport is the largest international airport in Russia in terms of passenger and cargo traffic, and is included in the TOP-5 largest hub airports in Europe. The area of the Sheremetyevo airport complex is more than 570 thousand m².
Sheremetyevo Airport has the most modern high-tech terminal infrastructure in the country, which allows it to provide high-level passenger and customer service.

Air quality monitoring in the Meridio office center. In a 15-storey building, on each floor in the left and right wings, wireless autonomous sensors are installed that monitor temperature and humidity. All readings are summarized in a single console for building maintenance services, alarm notifications are configured in the messenger and by e-mail. Proactive monitoring allows you to quickly identify a problem in the operation of ventilation machines or chillers. Now the tenants have become more comfortable to work.
About the accuracy of the readings
The accuracy depends on the range of the temperature value. In the Sensirion SHT41 sensor that we use, an accuracy of ±0.25°C is achieved in the range from -40°C to +65°C, and in the range of +65°C to +120°C it increases to ±0.5°C.
Similarly with relative humidity: at the "ends of the scale" from 0% to 10% and from 90% to 100%, the accuracy is ± 3%, instead of ± 2% (as with humidity in the range from 10% to 90%).
About the necessity of high accuracy
Our customers often have a question about the discrepancy between the readings of sensors located in the same conditions next to each other, for example, in the same box or in the same room. Indeed, the readings of a dozen sensors placed side by side may well vary up to ± 1 °C. This does not mean that the sensors have a low accuracy or gives incorrect data. All digital sensors are calibrated at the factory and cannot have such an error. To do this, autoclaves with a special liquid are used, which allows you to achieve really the same temperature.
To make sure that the sensors correctly measure the values, it is enough to check with a certified device. By the way, most of them also have digital sensors from Sensirion, but only the previous generation. We use the newest generation of sensors.
Also often try to compare the readings of accurate digital sensors with what is at hand - with sensors from Chinese manufacturers, weather forecasts, etc. Of course, this is not serious, because the accuracy of such measurements can reach 10%.
The experience of using digital sensors allows us to draw the following interesting conclusions:

The experience of using digital sensors allows us to draw the following interesting conclusions:
- The Sensirion SHT41 digital sensor is really very sensitive and accurate;
- High accuracy (detail) of measurement often raises more questions than it gives really useful information for monitoring;
- The readings of high accuracy (detail) will always differ in the same box, on the same wall, and even more so in the same room.
