WebbSince the output voltages of the thermopile are very low (in the µV-mV range), they are first amplified 10 times with an operational amplifier of the AD8551 type. You need an operational amplifier with a very low input offset voltage! Then the amplified voltage goes to the ADS1115 AD converter module. WebbThermocouples are temperature measurement sensors that generate a voltage that changes over temperature. Thermocouples are constructed from two wire leads made from different metals. The wire leads are welded together to create a junction. WebbThe function of a thermopile is to transfer the heat radiation emitted from the object to a voltage output. The output is in the range of tens or hundreds of millivolts. Thermopiles work as sensors or generators. As a sensor, the thermopile is used to determine a relatively low temperature (compared with normal thermocouple operations). physical therapy orthopedic residency program
