WP304D Intelligent Remote Temperature Collector

WP304D temperature collector adopts MEMS temperature sensor chip to be encapsulated in a specific case. The temperature sensor and the conversion circuit are integrated to form a small special temperature sensor. Its appearance is small and exquisite, the measurement accuracy is high, the reliability is good, the power consumption is low, and the circuit is integrated. And other features, as long as the 3.6V.dc battery is connected to work. The built-in circuit can perform linear calibration on the MEMS measurement sensor, and the measurement signal is proportional to the output. The digitized temperature value is sent to the MCU for digital processing and storage, and is transmitted to the cloud platform in real time through the NB-IoT wireless network. Finally, the cloud platform transmits the data to the APP user center to provide accurate and timely temperature parameters for process control. The product has a compact structure and is easy to install.

Precautions for sensor use

Platform function description

1. Normally report once a day, and report on-time data within 24 hours each time;

2. The platform can modify the reporting time interval, which can be set by the user, but pay attention to the battery life;

3. The user can set two alarm values, the upper temperature limit and the lower temperature limit. If the current temperature exceeds or falls below the threshold, the data will be sent to the platform immediately;

4. The platform supports short message notification to users or email notification to users (fees need to be paid), if the temperature alarms, it will immediately notify users by short message or email;

5. The platform supports data query and data export functions.

Normally report once a day, and report 24 hours on-time data each time (the platform can modify the reporting interval)

You can check the data in advance, use a magnet to sense the right side of the sensor box once, check after 1-2 minutes

Look at the platform data, the platform will receive the current time point data once.
