Agronode – Autonomous telemetry station with external sensors with radio transmission based on IoT technology.

Station is designed to collect, store and transmit wide variety of physical, chemical and other phenomenons from commercial sensors.

Device configuration can be changed to use wide spectrum of currently used IoT radio transport medias such as Lora, Sigfox, NbIot. 

Node can be also used as communication and backup module for complex systems.

• Measurement acquisition, publication and store is driven by user script
• Internal storage for up 250 000 records with ring buffer strategy
• USB and BLE user interface
• Powered by internal accumulator with solar charging or by primary battery
• Magnetic button with script interaction 
• ARM Cortex M0 ultra low power procesor
• Real time clock
• Integrated tilt sensor
• External antenna
• Inputs protected for overvoltage

External sensors (multisensors) are connected by combination (up 2) of buses:

• SDI12
• RS485
• 1WIRE
• I2C
• DIGITAL
• PULSE
• ANALOG VOLTAGE (5V, 10V)
• ANALOG CURRENT

Optional radio module

• LoRa
• Sigfox
• GPRS
• NbIot
• IQRF
• EGPRS/LTE M1/LTE NB2
