The emergence of the internet of things (IoT) has made various kinds of sensors an important part of the modern world. For instance, motion sensors, temperature sensors, and even gas sensors have all made great contributions to our daily lives. Among these sensors, the TMP104EVM is perhaps one of the most widely used. In this article, we will discuss the application field and working principle of the TMP104EVM.

Application Field

The TMP104EVM, or the Texas Instruments TMP104 temperature sensor, is specifically designed to measure temperatures ranging from -50°C to +150°C in industrial, commercial, and consumer applications. The device is fully calibrated and has a programmable digital output that supports both analog and pulse-width modulation (PWM) outputs. This makes it well-suited for a variety of temperature sensing applications, such as medical instruments, HVAC thermostats, automotive, and industrial process control.

In addition, the TMP104EVM can be used in a variety of data logging/monitoring applications. It can be used to track temperature changes over time in order to detect anomalies in environments, or even to monitor changes in climate. The device is also well-suited for use in remote access applications that require reliable data transmission. Finally, the TMP104EVM is well-suited for use in hazardous or hazardous locations, where the device can be safely monitored from a distance.

Working Principle

The TMP104 temperature sensor consists of an on-chip temperature sensing capacitor, current source, and resistor. The on-chip temperature sensing capacitor converts the temperature into a voltage that is proportional to the temperature. This voltage is then converted to an output signal by the current source and resistor, which is then compared to the nominal voltage value to determine the temperature.

The TMP104EVM is also capable of providing an independent temperature measurement with a resolution of 1°C. This is achieved by measuring the frequency of the output signal, which can be programmed to range from 0 to 63 Hz in 1/16th Hz increments. The result is a highly accurate measure of temperature which can be used in a variety of industrial and commercial applications.

Finally, the TMP104EVM is also capable of providing a remote monitoring function. The device is equipped with a voltage-control signal input, which enables it to accept commands from a remote source. This allows the device to be monitored from a distance, providing greater flexibility for temperature sensing applications.

Conclusion

The TMP104EVM is a versatile temperature sensor that can be used in a variety of applications. It has a wide range of applications including medical instruments, HVAC thermostats, automotive, industrial process control, and data logging/monitoring. The device is also capable of providing an independent temperature measurement with a resolution of 1°C and a remote monitoring function with a voltage-control signal input. The TMP104EVM is thus an ideal choice for a wide variety of temperature sensing applications.
