Utilizing the latest NB-IoT wireless transmission technology, VWdot is a datalogger that can measure frequency and thermistor temperature signals of vibrating wire sensors.
The housing is designed with a robust and waterproof enclosure that complies with IP65 standard. VWdot is able to sustain long-term measurement and instant data upload because of its low-power consumption which is merely using a 18650 Li-ion rechargeable battery. It is able to back-up and store more than 1 million of recorded data with its built-in 16 GB SD card. Therefore, VWdot is not only a wireless datalogger but also a stand-alone system where there is no NB-IoT service.
VWdot is a reliable, cost-effective datalogger developed for all kinds of vibrating wire sensors and civil engineering applications.
