Sensor WLD, CO2 gas, 0 … 5000 ppm

Wireless sensor for NAWI with display (WLD = wireless sensor with display).

Thanks to its integrated colour display, this WLD sensor is also a standalone digital measuring device. Simple measurements therefore take only a few seconds.

The display shows the following parameters:
.) Measuerment value
.) Unit of measurement
.) Connection status (mobile or PC)
.) Sensor ID
.) Battery capacity and charge status

Of course, this WLD-SMART sensor can also be used wirelessly via Bluetooth or wired via USB with the free "Science#" app on mobile devices such as tablets or iPads (Android or iOS) or computers (Windows or Mac).

A single button press is all it takes to display other measured values (only for sensors with multiple measuring ranges or multiple built-in sensor types) or to calibrate sensors.
Up to 4 sensors can be used simultaneously in BT mode.
Display: 0.96" OLED colour display (128 x 64 pixels)
Power supply: Li-poly battery (3.7 V 700 mAh)
Operating time 4 to 22 hours with a fully charged battery (depending on conditions of use)
Connection: Bluetooth 5.0 Low Energy (BLE) (Mac, Android, iOS) - and Bluetooth 2.1 Classic (Windows)
USB 2.0 (Type C)

Delivery includes USB-C cable for charging the battery, data transfer or wired measurement for a higher sampling rate.

For measuring the concentration of carbon dioxide in the air or in enclosed spaces.
Also suitable for measuring the amount of carbon dioxide produced by the respiration of small creatures such as crickets.
