This is an input type liquid level acquisition terminal based on LoRaWAN, which adopts LoRa spread spectrum modulation technology and has the characteristics of ultra long distance communication, ultra-low power consumption, stability and reliability. Built in high-precision water level sensor with a range of 0-5 meters (customizable) and an accuracy of ± 0.5% F.S, supporting threshold active reporting and remote wireless configuration. Suitable for liquid level monitoring in environmental protection, water conservancy, variable frequency water supply, industrial process control, smart factories, smart construction sites and other scenarios. Supports standard LoRaWAN and ModBus protocols, with waterproof and anti condensation design. The liquid level probe can be quickly replaced without calibration.

ZONEWU LoRaWAN noise sensor is a high-precision sound level meter with a wide measurement range of 30dB to 130dB, perfectly catering to diverse daily noise monitoring needs. Boasting the inherent advantages of LoRaWAN technology—long-distance transmission, low power consumption and stable data connectivity—it is widely deployed across multiple scenarios, including home environment monitoring, office acoustic management, workshop noise control, automotive noise testing, and industrial on-site measurement.

Low-Power Wireless Temperature and Humidity Sensor, and based on LoRaWAN communication, strong compatibility, wide coverage and with multiple probes to choose from.
