BATTERY OPERATED SENSOR DEVICE
To build a battery operated autonomous sensor device capable of the following functionality:
Scope of functionality:
• Reading of the configuration from the SD card and application if it is different from the one already stored in the EEprom
• Taking the time reference (from GPS Ublox NEO 6)
• Reading the actual position (Lat, Long, Alt, - from GPS Ublox NEO 6)
• Reading the air particle sensor data (PLANTOWER 1003) (via serial interface Tx, Rx, Enable, Reset, 9600.8, N – TTL Levels - 3.3v).
• Read the Ambient Temperature, RH and BP (with BME280 sensor)
• Read the current voltage of the battery
• Transmission of the current data to the MQTT broker via Internet (if Wifi is connected and available – This behavior should be a parameter of config. as well) .
• Transmission of the current data via LORA (if Wifi unavailable– This behavior should be a parameter of config. as well).
• Capability to download the stored data via WIFI (Local AP)
• Capability to upload the stored data file via internet to a WEB site (receiving code to be developed as well)
• Storage of the data on the SD card (format in text, fields separated by commas)
• (Timestamp, Data)
• Storage of the configuration in EEprom and in the microSD.
• Device ID
• URL of the MQTT Broker
• Reading intervals for the sensors (for each sensor)
• Frequency -interval- of real time data transmission
• Data collection frequency for storage in SD.
• Capability to remotely change/update config
• Behavior of the data transmission (auto, via LORA, Via WIFI)
Capability to remotely change/update config via MQTT message
• Verify the operation of the software.
• Verify the functioning of communications
• Verify the integrity of power suspensions, interruption of communications, etc.
• Working developed software (carefully documented source code)
• Conections Diagram.
The design may use an Arduino, ESP32 or ESP8266, (most convenient, but keeping in mind cost-effectiveness, energy consumption and size).
• Lipo 16650 x 2
• 10 days to develop SW
