Wireless Sensors Link With iPads for Remote Data Collection

Vernier is adding new wireless sensors to measure pH and CO2 and remotely collect data and perform calculations on mobile devices, like an iPad.

The new pH sensor, called Go Wireless pH, can be used with Bluetooth devices, like an iPad or the company’s LabQuest 2, a touchscreen data collection tool, to perform experiments, such as investigating acids and bases and test water quality. When using an iPad, a separate app, called Graphical Analysis, students can perform statistical calculations and other analysis and export their data to other formats.

To measure CO2 gas concentration in air, Vernier is also releasing a new sensor, NODE+ CO2 Gas and Thermocouple, which are designed for use with its wireless sensor platform, NODE. The thermocouple can be used in extreme environments like liquid nitrogen, ranging from -200°C to 1200°C. It, too, is compatible with the Graphical Analysis iPad app.

"As we continue to develop and expand our Go Wireless family of sensors, teachers and students have more opportunities to utilize mobile devices as part of teaching and learning," said David Vernier, co-founder of Vernier and former physics teacher in a statement. "The new, cost-effective sensors allow for engaging, hands-on investigations across multiple science disciplines."
