How To Assembling 4 Digit LED Electronic Clock Kit Temperature
How to Build Your Own Electronic Temperature Monitor
An electronic temperature monitor contains a sensor that can get information from the physical world and transfer the analog data into digital data. The information can be flow-rate, change in pressure or temperature around the sensor. The way to get the data is to measure signals, which are current or voltage generated by the sensor. The signals are often weak and can be affected by external interference, so the temperature monitor requires an amplifier, which is an electronic device for boosting its signal level and blocking interference. The electronic temperature monitor combines sensor and amplifier so the device can get the physical data from the real world and convert the information into digital signal for display on a computer or voltmeter.
Connect the electronic components(see below) for the sensor parts.Make sure that the sensor is on the bottom right of the protoboard. Points A, B are the connecting points to the other parts of the device.
Connect the electronic components(see below) for the amplifier part.Make sure that the whole amplifier part is on the top left of the protoboard. A, B are the connecting points to the sensor part.
Adjust the resistance of each potential meter by using tool stick(see "things you'll need"), and make sure that resistance on each potential meter matched the "list of data".
Connect the temperature monitor to the power supply.Connect the end point of the amplifier to the voltmeter.
Turn on the power supply and make sure that the power is set to 12 volts.The voltage on the voltmeter will be the temperature in degrees Fahrenheit.
- Keep the wire as short as possible. This will decrease errors caused by interference.
- Make sure the sensor is far away from other electronic components. The components could be damaged while sensing high temperature.
Things You'll Need
Power supply, voltmeter and tool stick for adjusting potential meter. Required components: Potential meters(resistors), wire, protoboard, transistor, amplifier(model:OP27E) and sensor(model:MAT01AH).
