Why Choose NTC Thermistor? Brief Analysis of Its Application in Livestock Smart Ear Tag

In the development of smart ranch, monitoring livestock body temperature is a crucial step in disease prevention and improving production efficiency. Traditional livestock temperature checks are mostly done manually, making real-time monitoring impossible and hindering the immediate detection of health issues. As a result, smart ear tags equipped with EXSENSE NTC thermistor is increasingly favored by more and more ranch operators. Thanks to temperature monitoring with EXSENSE thermistor, smart livestock system can achieve "real-time collection—wireless transmission—cloud analysis" through smart ear tag, effectively solving the problems of low efficiency and high error rates associated with traditional manual temperature measurement.

EXSENSE smart ear tag NTC thermistor can quickly sense temperature, allowing timely detection of subtle changes in livestock body temperature. To ensure the accuracy and stability of temperature monitoring, the NTC is usually installed at the contact end of the smart ear tag, that is, meaning the area directly touching the livestock’s ear. This placement allows the thermistor to fit better with the ear skin and reduces interference from the ambient temperature. When the livestock‘s body temperature changes, the resistance value of the EXSENSE smart ear tag NTC thermistor changes correspondingly.The control circuit inside the ear tag converts the NTC resistance value into electrical signals, which are then transmitted via a wireless module (such as Bluetooth or WiFi) to terminal device, allowing user to monitor the livestock’s health anytime and anywhere.

The application of NTC thermistor in smart ear tag provides important technical data references for the development of smart ranch. Why choose EXSENSE thermistor as the temperature monitoring component of ear tag? This is due to its outstanding characteristics:

1. High accuracy, Building Reliable Data for Health Assessment

Even slight fluctuations in body temperature can indicate the onset of disease in livestock. The high accuracy (can reach ±0.5%) of EXSENSE NTC thermistor helps smart ear tags collect body temperature data promptly, effectively identifying early-stage diseases, reducing the risk of false alarms and missed diagnoses, ensuring the authenticity and consistency of temperature data.

2. Small Dimension, Promoting Development of Comfortable Wear

The sensing head of the EXSENSE smart ear tag NTC is small, allowing integration with other components within the limited space of the ear tag. This saves installation space and controls the weight of the ear tag, ensuring that the livestock can wear it without discomfort and avoiding stress reactions caused by improper wear.

3. Excellent Sensitivity, Capturing Early Abnormal Health Signal

EXSENSE NTC thermistor is highly sensitive and can quickly respond to temperature changes, continuously monitoring abnormal fluctuations in livestock body temperature and providing valuable time for early disease detection.

By continuously monitoring and recording livestock body temperature with EXSENSE smart ear tag NTC thermistor, smart livestock system gains a precise and reliable basic temperature data sources. This information can not only be used for timely alarms but also serves as a strong basis for subsequent health trend analysis of the livestock.
