Blue Maestro Prepares Release of New Bluetooth-Enabled Sensor Products

The provider of Tempo wireless environmental sensors is launching a waterproof temperature sensor that acts as a data logger, as well as a BLE-enabled temperature-measuring pacifier, a small mobile sensor and a Wi-Fi-based hub.

Blue Maestro was launched two years ago in the United Kingdom to provide wireless sensors to track temperatures and other environmental conditions. With the adoption of Bluetooth Low Energy (BLE) technology in the iOS 6 version of the Apple iPhone, Blue Maestro commercially released a BLE-based version of its Tempo sensor. The battery-powered device measures temperature, humidity and air-pressure levels, as often as 24 times an hour, and transmits that data—via a Nordic ID nRF51822 Bluetooth Smart chip utilizing BLE technology—to a smartphone operating the Tempo app. Measuring 3 inches by 3 inches in size, the device is designed to be easily moved from one room to another at a home or business, or outdoors (as long as it does not become immersed in water), in order to capture sensor data and then transmit that information to a phone at a distance of up to 50 meters (164 feet).

To date, the Tempo product is being used primarily by consumers. The company has found that many of its customers own snakes, reptiles or other exotic pets that must live at specific temperature and humidity levels to survive. Those customers place a Tempo device within a tank, where it transmits data to a user's phone located elsewhere in a house or building, so that they can be alerted if conditions become unhealthy for their pets.

However, at the 2015 Consumer Electronics Show, held this week in Las Vegas, Blue Maestro announced the pending release of a device with a business-application focus: a BLE-enabled smart temperature sensor and data logger known as the Tempo Disc. The waterproof device, which will have an IP67 rating and feature a replaceable coin battery with an expected one-year operational life, could be used in scenarios such as the monitoring of environmental conditions of perishable goods as they are transported or stored. Mohamad Foustok, Blue Maestro's CTO, expects the Tempo Disc to be made commercially available in April of this year.

In early 2014, Blue Maestro was looking into other use cases for wireless sensors, and determined that there was a market for an application that would let parents monitor a baby's health via a temperature-sensing pacifier. Other companies have already created thermometers or temperature data loggers built into pacifiers, Foustok says. Those devices typically come with an LCD display on the front to show the temperature reading for parents, but they do not transmit that data.

To make the collection of temperature data more convenient for parents, Blue Maestro launched Pacif-i. The pacifier, like the Tempo, comes with an nRF51822 Bluetooth Smart chip that transmits the information via BLE to a free Blue Maestro app loaded on a user's phone. Pacif-i also contains a thermistor to measure temperature levels, a buzzer that will sound if it ends up missing (assuming a phone user operating the app inputs a request for it to buzz), and a battery to power the temperature sensor and Bluetooth transmitter. The company is now selling the product in limited quantities, and expects to support large-volume commercial sales in January. Current Pacif-i customers are using an app provided to them directly by Blue Maestro, while the app is slated to become available at Google Play and iTunes this month as well.
