Miniature Modular ThermometerIn our everyday life, ambient air temperature is very important for all of us. Whether you are getting dressed in the morning to go to work or for a walk, you need to know ambient temperature so that to decide what to put on.Today, the most widely used temperature instrument is obviously a thermometer. Alcohol or liquid thermometers enjoy the greatest popularity as they are easy-to-use and offer high measurement accuracy. However, digital thermometers are gaining popularity that they do not have such shortcomings as fragility and non-repairability. Besides, you don't have to place the thermometer at the measurement point.Thermometers come in various types from complex and expensive electronic weather stations that are able to measure humidity and pressure in addition to the ambient temperature or even communicate with satellites to simple cheap electronic thermometers that measure only one or two temperature values.For example, let me demonstrate a two-channel miniature modular thermometer with 5x7 mm animated LED indicator, model MP503 BLUE.Temperature readings are taken from the two temperature sensors DS18B20 that are not included in the delivery package.The thermometer is powered from any suitable power source with the voltage ranging from 7 to 24 Volts. It consumes only 55 mA. That's why you can use a nine-volt battery as a power source for a long time. The device has the dimensions of 38x25 mm only.Let's unsolder two temperature sensors and connect them to the thermometer. Then, let's power the thermometer.The main feature of this miniature thermometer is a 5x7 pixel LED matrix. It indicates three significant digits and the separation point. Information is displayed in the form of a running line.The measured temperature comes up from the right and the left side of the indicator alternately with the frequency of about 1.2 seconds. Positive temperatures are displayed accurate to one decimal point while negative temperatures are shown as integer numbers with a minus.Its small size, wide range of supply voltages, two temperature sensors, and a smart indication method makes this thermometer a perfect solution for simultaneous measurements of air temperature indoors and outdoors or inside and outside the car's salon.You can also use this modular thermometer as a design element for PC modding cases
