Bluetooth Smart Temperature Sensor
Ultra-low power (ULP) RF specialist Nordic Semiconductor ASA (Oslo, Norway) announced that British startup, Blue Maestro, has specified a Nordic nRF51822 System-on-Chip (SoC) in each of its GBP £29 ($50) 'Tempo' Bluetooth Smart (Bluetooth low energy) temperature sensors that allow consumers to accurately measure and monitor air or water temperature 24x7 anywhere in their home or business, from a smartphone. Features include:
- Maximum operating range up to 250-ft.
- Temperature is measured using a high accuracy thermistor that monitors air or water temperature in the immediate vicinity of the Tempo to allow even subtle variations to within ±0.2oC to be immediately detected.
- Tempo advertises current temperature once every two seconds and records temperature in its memory once an hour over the previous 24 hours so users not-in-range can track the temperature behavior when they are next in range through a free Android or iOS app.
