AQ with IP68 integrated pressureTwo-way communicationLocal USB and Bluetooth communication Battery power supply for more than 7 years (standard 2 batteries, optional 3) Battery exchange option Mains power option External or internal antenna 3 x digital or analogue inputs (4-20 mA or 0-3 V) and RS485/Modbus Option of relay for valve or switch control Option with connectors to facilitate wiring For devices that need to be "online", the mains or solar cell power option are used Developed in a rugged IP68 enclosure, the AQ IoT Data Logger is designed for use in harsh environments. The device has an integrated modem for two-way communication and battery power in the form of three D batteries which is sufficient to send data at intervals for more than 7 years. Sustainability values have been key in the design. Batteries can be replaced and in the event of failure of the electronic components, only the cover of the device with the electronics needs to be replaced, leaving the cable connections to the sensors intact. The AQ device has a pressure and temperature sensor built into the housing which is connected directly to the rubber hose from the water supply (option of two pressure and temperature sensors). There is an additional option to connect a flow meter or other device. The device collects data and stores it in an internal memory which can be changed at will from 0.01 seconds up to one month. The sending time can be selected independently - from 1 minute up to 1 time per month. The device can be configured with a USB cable or Bluetooth interface via the AQ Setup software or remotely via the AQ WEB app. The settings can be kept factory default (saving data every 30 minutes and sending 2 times a day). On AQ IoT devices, hardware alarms can be set for each input separately - manually, retrospectively via the AQ WEB interface, or set automatically by AQ WEB using an algorithm. With a hardware alarm, the system notifies us as soon as it happens. When the number of pulses or the analogue value is exceeded, the machine sends an alarm to the server and the AQ WEB then forwards it to the user by SMS or email. In this way we are always informed at the same moment when a pipe bursts or something unforeseen happens. The AQ IoT Data Logger can also be equipped with a relay output, allowing us to open/close a valve or switch online. When used in combination with a PRV valve, it is possible to create standard or custom-built algorithms to control the system.
