Everyone is familiar with the principle of a conventional thermometer. Someone still enjoys indoor thermometer, for some it is important to check the outside temperature before leaving the house. Over time, changing design, product complemented by interesting features. Here and now manufacturers are pleased with another novelty, releasing an electronic thermometer with a remote sensor. The case is set at home, and a device that detects the temperature of which is located outside. We will understand the principle of operation, advantages and disadvantages of the device, and the ability to manufacture its own.

Scope of electronic thermometers with remote sensor

The presence of the remote device expands capabilities of the device. But its main purpose - to control the temperature inside the house and outside. If you compare it with a mercury thermometer, electronic indicators most closely identifies.

Electronic devices used:

• in industrial production;
• set in aquariums;
• in paragraphs animal welfare;
• warehouses;
• at saunas and bathhouses;
• in cars.

Electronic thermometer with remote sensor: and how the functioning principle

To make the best use of all the functionality of the product, you should consider its structure and understand how it works. Room thermometer consists of two parts:

• housing with a display. It is designed for indoor installation;
• remote device, which should be placed within 65 meters of housing.

electronic device It does not require special conditions for use. The thermocouple, which is sensitive to changes in temperature, is enclosed in a shell of metal, plastic or rubber. The pulses coming from it to the block, which is installed indoors.

Manufacturers produce two versions of the electronic thermometer to measure the temperature of the outside air: wired, with a length of wire up to 3 meters, and wireless. In recent sensor installed outside, inside which a thermocouple is placed.

Temperature readings are displayed on the display main body. No need to peek out or wipe window from frost.

Specifications of electronic thermometers

you should know before you buy a thermometer with all models and technical parameters, as well as additional features that make measuring more convenient in everyday use. The main characteristics of the electronic thermometer:

• inner housing operates at temperatures from -10 to + 50 ° C;
• constraint in a temperature range outside -50 to + 70 ° C.

A wide temperature range allows you to use a digital thermometer with a sensor in all corners of Russia. Sealed housing and a remote device is not afraid of high summer temperatures, direct sunlight, winds and torrential rains, and severe frosts.

Rules of operation of the thermometer with remote sensor

Terms thermometer wireless operation with an external ambient temperature sensor arranged in the instructions for use. In a few words, you can highlight the main ones:

• the device must be checked for damage before the first use;
• recommended operating conditions must be met;
• external temperature sensor can not be stored for a long time in direct sunlight;
• if the thermometer is not used, it should remove the batteries.

It is important! In case of trouble you need to have your computer serviced. Not recommended to repair it yourself.

Variety of digital thermometer with remote sensor

Electronic thermometers with probe are divided into:

• board. Model set at any convenient readout horizontal surface;
• wall. The apparatus is mounted on a vertical surface in a public place. Modern thermometers feature a stylish design and are suitable for any interior decoration;
• portable. Their size is no longer a mobile device.

Outdoor window thermometer with remote sensor

During the selection of a thermometer with an external probe is necessary to pay attention not only to technical parameters, but also by the presence of additional features.

Especially electronic devices

Remote Probe installed not only on the outside. It can be used to measure the temperature in other rooms. Modern devices, not only will lead indicators on the screen, but also to analyze them using the monitor. It is not necessary to install them near the window openings.

Basic and advanced features

Modern electronic outdoor thermometers are equipped with additional features that also enhance their value. It is therefore necessary to determine when buying their feasibility.

Electronic thermometer with remote sensor for the bath

for baths an important indicator, in addition to temperature, is humidity. To measure and maintain the desired mode device with remote sensor - it is the best instrument because of its technical parameters.

Features, advantages and disadvantages

Manufacturers produce a wide range of temperature meters with remote sensor. When you select should follow a few tips:

• you can choose the product both wired and wireless. Wired probe installed in the steam room, the main unit - in a waiting room;
• for steam is recommended to get thermometer-hygrometer;
• necessary function - the presence of an audio signal when the required heating parameters.

Main functions

Electronic model for measuring the temperature and humidity It must be equipped with the following main features and characteristics:

• withstand the temperature range from -50 to + 200 ° C;
• one housing can be connected to three probe;
• remote probes should be at a distance from the block no more than 40 meters;
• Housings thermometers are made of durable plastic and steel;
• products allow error of not more than 0,5 ° C.

The humidity sensor as an optional feature

Moisture - not less important factor, along with the temperature. Only the knowledge of two parameters allow you to set the most comfortable mode in the steam room. If humidity is high, the temperature must not rise above 40 ° C. If the moisture content is reduced, it is possible to raise the temperature in a steam bath to 80 ° C. These indicators will help to create a healthy climate in bath.

Correct installation position of the thermometer

In order to get the maximum benefit from the electronic device operation, you need to follow two guidelines:

• wall model is fixed on the wall at a distance from a floor of 1.5 meters;
• location for the main unit to be at the same distance from window, doors, Steam room, fireplace.

An overview of measuring instruments

Each product has its pros and cons. When buying street electronic thermometer with remote sensor to look at the temperature range. Consider the most popular gauges from different manufacturers:

• model RST - operates at high temperatures;
• Sawo model - a wide range of interesting shapes and sizes.

If we compare the turnouts, capillary or digital devices, the choice should be stopped at the last. Electronic digital thermometers are safe, their readings more accurate, but the cost is slightly higher.

How to make an electronic thermometer with their hands

If desired, you can understand the nuances of the manufacture of digital thermometer with their hands. The finished product will be connected via USB to a laptop. Furthermore, it is possible to connect multiple remote sensors to a single block, it will reduce the cost of consumable items.

The necessary parts and tools

You will need the following details:

• One or more temperature sensors (Dallas SD 1820, for example);
• 2 Schottky diode;
• zener at 3.9, 6.2, 5.6 V;
