[0002] The optical fiber temperature measuring device is a device that uses optical fiber as a sensing element to measure temperature. Its working principle is based on the fact that the spectral characteristics of certain substances will change with the change of temperature. By analyzing the spectral information transmitted by the optical fiber, the real-time temperature value can be determined. The agricultural optical fiber temperature sensing device can be used to realize real-time monitoring of the temperature inside the farmland and the greenhouse. By laying optical fiber sensors in the farmland or greenhouse and using the thermal sensitivity of the optical fiber, the changes in parameters such as soil and air temperature can be measured with high precision, providing temperature data support for agricultural production.
