CMA Wireless Sensors can be used to measure without an interface. They are simple, user-friendly, and offer more mobility and flexibility. They can be used anywhere without the need for power or wired connections and are suitable for a wide range of student experiments.
Connectivity: The sensors operate wirelessly via Bluetooth or wired via USB and can be used with a variety of devices: computers, Chromebooks and mobile devices.
Display: The sensors are equipped with a color OLED screen which displays the battery level and the measured sensor value. This unique feature makes the sensors suitable for use as independent measuring devices.
Battery: The sensors have a large battery capacity and a smart way to save power by automatically turning off when they’re not used. They can be used an average of 12 hours without needing to be charged.
School Level:
- Wireless sensors offer distinct advantages in various STEM experiments compared to their wired counterparts, primarily due to increased mobility, convenience, and flexibility.
- Wireless sensors can be a great addition to your data-logging equipment for use in outdoor environments, to measure different quantities without the constraints of wires or for monitoring chemical reactions without getting too close to dangerous substances.
- Wireless sensors are easy to use, and CMA wireless sensors are especially convenient because they have their own display. In other words, you can use them as measuring instrument even without software.
In general Wireless sensors have some limitations compared to our high-quality interfaces and wired sensors.
- The sample rate of a wireless sensor is limited.
- A battery needs to be charged at the time of use.
- Interruptions or signal loss that wireless connections can sometimes cause.
- Cost, the prices of wireless sensors are higher, they have their own processor, display, rechargeable battery and Bluetooth.
When compared with wireless measurements with WiLab, the sample rate of a wireless sensor is much more limited than the sample rate of WiLab. By default, the sample rate has a maximum of 100 Hz, and with WiLab it is 100,000 Hz.
CMA Wireless Sensors can be used as independent measuring instruments and can connect to a wide range of devices, including computers and mobile devices.
