To promote good conduct and health, HALO smart sensors were installed in the high school and junior high bathrooms in October.
“Because they check air quality, we purchased them in response to COVID-19,” Dr. John Sherrill, high school principal, said.
Technology Director Karen Brunker said the sensors can detect a multitude of things such as tampering, vape, THC, vape masking and aggression.
“All these qualities are to keep kids safe and detect issues where we don’t have cameras,” Brunker said.

Sherrill said the district paid $6,500 for six sensors.
“Grapevine ISD gave me a good recommendation for the HALO sensors,” Sherrill said. “We had a campus improvement team approve the idea in May and purchased the sensors over the summer. “
As part of its Air Quality Index measurements, HALO monitors carbon dioxide, volatile organic compounds, nitrogen dioxide and other particulate concentrations in air.
“The sensors were paid for with ESSR funds, which are federal stimulus given to schools to finance COVID-19 responses,” Sherrill said.
Sophomore Mary Hicks said she thinks they are useless.
“I don’t think they’ll be effective with one in each bathroom, and I don’t think the results will be substantial,” she said.
