Hardware Component Features
Smart Spot main
board V1.4
• Gas Board connector.
• 5x HOP Expansion Board connector.
• 1x SPI and 1x UART connectors.
• RGB LED.
• Reset Factory Button.
• BME280 (temperature/humidity/pressure).
• MPU6050 (Accelerometer/Gyroscope).
Antennas
• External WiFi 802.11 b/g/n/e/i (STA-AP) / Bluetooth Low Energy Antenna.
• External GSM/GPRS Antenna (Cellular).
• Internal GPS Antenna to provide precise location of the device.
GSM (SIMCom 868)
• Quad-band 850/900/1800/1900MHz.
• GPRS multi-slot class 12/10.
• GPRS mobile station class B.
• Compliant to GSM phase 2/2+.
◊ Class 4 (2 W @ 850/900MHz).
◊ Class 1 (1 W @ 1800/1900MHz).
• GPRS class 12: max. 85.6 kbps (downlink/uplink).
• Coding schemes CS 1, 2, 3, 4.
• Micro-SIM card slot (15mm x 12mm – 3FF).
Gas Sensors Extension
• Integration of the Advanced Air Quality Monitoring board to allow to observe gas
concentrations (NO2, SO2, O3, CO, H2S) based on Alphasense sensors.
• Measurements from 0 to 10 particles per million (ppm), covering from PM1, PM2.5
and PM10 particles ows.
• Sensors sensibility is greater than most of the manufacturers.
• Response time of the sensors is about 60 seconds, depending on the sensor.
• Temperature range -20 °C to 50 °C.
• A fourth electrode is included to improve temperature correction. The electrode
output current does not change with the gas concentration. Thereby, offering a ne
tune eld calibration.
Noise pollution monitoring
• Developed under the conditions of the international standard IEC-61672.
• Dynamic Range from 40 to 130 dB.
• Quality Category: A-frequency weighting.
• 0.1 dB Resolution.
Temperature/humidity probe • Measure ambient temperature and humidity.
