Description

Application area

The device relates to electronic thermometers and can be used to measure air temperature behind glass on the street or inside special rooms.

State of the art

The advantages of glass-mounted thermometers with a clear display are obvious. This makes it easier to get information about the temperature outside, getting information in a more readable form (visibility from a few meters from the window), no need to drill a window frame for mounting a thermometer.

The closest analogue is a street thermometer with a transparent display according to the patent DE 202005005017U. The thermometer is mounted on the window from the outside. It has the function of monitoring the maximum and minimum temperatures during the day.

This thermometer consists of a holder, inside which a microprocessor, a temperature sensor and a battery are integrated, and a transparent liquid crystal display. Moreover, the holder is located on top of the display and serves as a roof for it from the negative effects of precipitation and sunlight.

The disadvantage of this thermometer is the need to replace the battery, which requires removing the cover from the holder. In addition, due to the fact that the holder is equipped with a removable cover, moisture easily gets inside the thermometer, which contributes to the rapid failure of the battery and corrosion of contact surfaces. Another disadvantage is that the thermometer will be subject to temperature distortion under the influence of the fact that the temperature sensor will come into contact with the elements of the holder body.

The technical result of the claimed device is the complete autonomy of the thermometer - it does not need to replace the battery, eliminating distortion

temperature readings, as well as the electronic part of the thermometer is completely tight, which eliminates the ingress of moisture.

Device essence

The claimed technical result is achieved due to the fact that (see Figure 1) an electronic thermometer consisting of a transparent liquid crystal indicator (3) and an electronic part (4) containing at least one temperature sensor, differs in that the electronic part of the thermometer and indicator made on a self-adhesive transparent base (2), the function of which is to fasten to the glass, and a solar battery (7) is installed on the back of the indicator on the electronic part of the thermometer. The electronic part of the thermometer additionally contains a battery (5) that is resistant to low temperatures, a microcircuit (6) for controlling the thermometer and the battery charge (5) from the solar battery (7). One of the temperature sensors (9) is thermally insulated from the main body, and the other (8) is thermally insulated from the main body and the environment. On the front side of the indicator on the electronic part of the thermometer, the surface can be mirrored. The liquid crystal indicator (3) works “in the light” and is made resistant to low temperatures.

The electronic part (4) of the thermometer contains a battery (5), for example, a Li-Ion battery that is resistant to low temperatures.

The microcircuit (6) controls the thermometer and the battery charge (5) from the solar battery (7). It also reads the readings from the temperature sensors (8 and 9), and calculates the true temperature using a tabular or other algorithmic method, based on the difference in the readings of the temperature sensors (“detects” the incidence of sunlight). Sensor (8)

thermally insulated from the main body and the environment (has a mirror coating), and the sensor (9) is thermally insulated only from the main body (4), but is not isolated from the environment (has a dark coating that effectively absorbs sunlight).

The result of these readings is a more accurate estimate of air temperature. The solar battery (7) charges the main battery (5) by means of a control microcircuit (6). The solar battery (6) itself is located on the side of the indicator on the electronic part of the thermometer (see Figure 2 (b)) and the consumer does not see it (see Figure 2 (a)).

To give the thermometer a more inconspicuous appearance on the glass, it is possible to mirror the front part of the body (4) of the electronic part of the thermometer that the consumer sees
