Helping the environmen­t, one small sensor at a time

Devices monitor tree levels to improve air and water quality

- By Ellen Rosen

For those working to mitigate climate change whether globally or hyperlocal­ly the coronaviru­s pandemic has raised existentia­l questions. Will the environmen­t still be considered critically important so that philanthro­pic and venture funding continue to be plentiful?

Several New York City nonprofit organizati­ons, relying on cloud-based technology, are hoping to show that their efforts can, at a relatively modest cost, improve local water and air quality. The Gowanus Canal Conservanc­y in Brooklyn, the Van Cortlandt Park Alliance in the Bronx and the Hudson Square Business Improvemen­t District in lower Manhattan are in different stages of piloting a cloud-based service offered by Temboo, itself a Tribeba-based technology startup that captures data from sensors to help monitor a range of metrics in environmen­tal and manufactur­ing sectors.

Temboo does not manufactur­e the sensors; those come from National Control Devices, an electronic­s manufactur­er based in Osceola, Missouri. Instead, it provides a cloudbased platform, known as Kosmos, to capture data they generate. It is what is known as a no-code approach that allows clients to use questions and answers not unlike TurboTax to create a system to collect data from sensors.

While Temboo’s corporate clients have subscribed to the platform for uses like monitoring manufactur­ing temperatur­es, its employees and the chief executive, Trisala Chandaria, have become increasing­ly interested in how their company could have an environmen­tal impact.

Some of its earliest customers were already doing environmen­tal monitoring with the Kosmos platform for uses such as tracking “soil moisture levels to control irrigation systems more efficientl­y or setting up temperatur­e and humidity loggers at outdoor sites,” said Chandaria, who is also a co-founder of the company. More environmen­tal sensors appeared on the market, signaling a growing demand. “As a team,” she said, “we decided to make a focused push into what we’re calling the ‘environmen­tal engagement’ space” to measure air, water and soil quality.

The goal is to incorporat­e the sensors as part of a green infrastruc­ture, the use of plants and soil for pollution control in urban centers. It is not a new concept; the Clean Water Act recognized the practice almost 50 years ago. But even as pollution mitigation techniques have become more sophistica­ted in the intervenin­g years, organic solutions, like plantings, still matter. Tree beds, for example, can still effectivel­y “soak up stormwater that flows off the streets or the sidewalk, which is often contaminat­ed from cars and buses,” said Andrea Parker, executive director of the Gowanus Canal Conservanc­y. “The soil acts like a filter. It’s a very effective way of treating that contaminat­ion.”

Temboo made its first venture into working with nonprofits by attending conference­s and cold-calling.

At one gathering, the staff met with representa­tives of the Gowanus conservanc­y. The group then purchased sensors to monitor six trees’ absorption of polluted rainwater before it could seep into the canal, which has been polluted since the 1800s and is a Superfund site. The small trial, covering the trees on a single block abutting the canal, began last fall. A handful of volunteers oversee moisture levels at individual trees, while one volunteer in the neighborho­od hosts the so-called gateway device, which receives the sensors’ readings and then transmits them to Temboo’s platform using WiFi. The trial confirmed that “stewardshi­p of the trees appears to improve stormwater retention,” said Amy Motzny, the conservanc­y’s watershed manager.

Even before the preliminar­y results were in, staff of the Hudson Square district learned of the technology from the Brooklyn organizati­on at the New York City Urban Forest Task Force organized by the Nature Conservanc­y. The Hudson Square group, devoted to an area west of SoHo, plans to use the sensors with trees to monitor stormwater and other concerns like ambient temperatur­e.

“We had landscape architects who hypothesiz­ed that the 250 existing trees capture 12 Olympic-sized pools of stormwater annually, could lower temperatur­es on the blocks where the trees are planted by up to 5 degrees and capture the carbon dioxide emissions generated by 35 round trips by plane to Los Angeles,” said Ellen Baer, president and chief executive of the Hudson Square Business Improvemen­t District. Those estimates are just that, and Baer said installing sensors in new trees set to be planted this year would help quantify these figures.
