Vernier Adds New Sensors to Environmental Science Equipment

Scientific data collection company Vernier Science Education recently rolled out two new sensors to its lineup of equipment for high school and college environmental science. The sensors are wireless and connect to student devices to collect and analyze data.

The Go Direct Pyranometer measures electromagnetic radiation in watts per square meter in the infrared, visible, and UV ranges. This sensor is particularly suitable for reading and analyzing solar cells and their efficiency, the company said. The pyranometer page outlines specs and requirements.

The Go Direct PAR (photosynthetically active radiation) sensor measures photosynthetic light levels in both air and water, reporting on photosynthetic photo flux density from both sunlight and electric light. It has a waterproof sensor head useful for "agricultural science, biology, and environmental science applications, including experiments investigating photosynthesis and primary productivity," Vernier said. This device page also lists its specs and requirements.

Both of these sensors connect to students' mobile devices, Chromebooks, or other computers, with the Vernier Graphical Analysis Pro app. They can be used wirelessly via Bluetooth or wired with a micro USB cable, included. Both sensors include a rechargeable battery. Each device costs $299.

The app allows students to time mark events such as sunrise and sunset, and they can perform experiments and share and analyze data in real time either on site or remotely.

"These sensors give educators new ways to study solar energy and photosynthesis with their students," said John Wheeler, Vernier CEO. "Whether investigating how energy varies with clouds or the process of photosynthesis in aquatic and terrestrial environments, educators can engage their students in meaningful, hands-on learning with real world applications."
