Sensor beacon with temperature, humidity (SHT20) and acceleration (LIS3DHTR) sensors. Same as M52-SA except with a larger CR2477 battery and slightly larger case. Comprehensive product that can be used in many different modes: 1 channel advertising, 2 channels advertising, 1 + 2 advertising, sensor advertising and Meeblue fixed data. The two main advertising channels can be iBeacon, Eddystone UID, Eddystone URL or user defined. When sensor advertising, the main channels are disabled and advertising includes a unique id, temperature, humidity and battery voltage.
The accelerometer is only used for motion triggered broadcast and has adjustable threshold (32mg to 2032mg). The accelerometer is not available in advertising data.
The sensor detects 0 - 100% RH, ±3% typical, ±4.5% maximum (20% - 80% RH) and ±4.5% typical, ±7.5% maximum (0% - 100%), -40°C to 60°C 0.3°C / ±0.5°F typical, ±0.5°C / ±0.9°F maximum (0°C - 60°C), 0.7°C / ±1.3°F typical 1.2°C / ±2.2°F max (-40°C to 60°C).
This beacon can also work as a sensor logger storing up to 312K (80985 records) of temperature/humidity data with a configurable storage interval of 1-240 minutes. Can store up to 56 days with a 1 minute storage update, available as files from the configuration app. Takes about a minute to download 80895 records.
Uses the energy efficient nRF52832 for a longer battery life. Pressing button in centre of beacon case can be used for button triggered broadcast. LED light flashes when turned off and on.
Available in black only.
iOS and Android configuration app.
Can be used with the free MeeBlue Platform to collect data.
