iWSN-3020-TC-BT-IP65 and iWSN-3020-TCF-BT-IP65 are wireless temperature sensing modules in the iWSN series, providing IP65 dustproof and waterproof rating, 433 MHz wireless communication interface and supporting 2-channel K-Type Thermocouple temperature measurement, and will actively and periodically transmit the measured temperature back to the iWSN wireless data concentrator. The main difference between the two modules is that they have different temperature measurement ranges and accuracy, making them suitable for different application scenarios. The temperature range of iWSN-3020-TC-BT-IP65 is 0℃ to 150℃, and its accuracy is ±2℃. The iWSN-3020-TCF-BT-IP65 has a wider temperature range, from 0℃ to 1300℃, and has higher accuracy at ±1℃.

In addition, both modules have built-in disposable lithium batteries for power supply and do not require an additional external power supply. They are suitable for applications in environments with extremely thick dust, no external power supply, and difficult wiring to achieve true wireless deployment. Moreover, this module can be set with 16 wireless channels and 4 group IDs, which can be divided into 64 wireless sub-networks in total. This facilitates the management and controlling of  433 MHz wireless data collection. Users only need to adjust the dip switch to complete the settings, making the module easier to adjust and maintain.
