The BEEP PCB

At the heart of the BEEP base is the PCB. This printed circuit board contains all connections for the sensors that are included in the BEEP base - temperature, sound, weight - and offers space for more. With the BEEP PCB you can design your own measurement system. 

The BEEP PCB is supplied in a splash-proof box and a connected temperature sensor, LoRa antenna and activation magnet.

Technical details

The PCB has been especially designed and produced for BEEP. Because of the purpose of the BEEP base, it is crucial that the energy usage is very low. It is based on the Nordic nRF 52840 64 MHz ARM®️ CortexTM-M4. It can collect data every 15 minutes for over 1 year on 2 AAA batteries. You can adjust the interval in the iOS or Android BEEP base app. In sleep, it uses only 4,5 μA. With its 64 Mb of memory the BEEP base can store two years of sensor information. 

Furthermore it consists of:

  • over the air firmware updates (BLE)
  • LoRa RFM95 868 MHz (EU) with uFL SMT antenna with wireless configuration
  • 1Wire 1-5x sensor (DS18b20)
  • audio ADC (92 dBA SNR) + AGC with 3.5 mm jack input with 4 pins
  • 2 channel weight amp (HX711) screw terminals
  • a low power 3V regulator
  • I2C screw terminals
  • unique hardware key IC
  • magnetic reed switch
  • tilt switch
  • buzzer
  • 2x AAA battery holder and, last but not least
  • Size: 75x50x23mm. 

The BEEP PCB comes in a watertight box (83x58x33mm) and a magnet to activate the BEEP PCB. 

Adding sensors

You can add sensors to the PCB to collect data in and around your hive. The current firmware supports:

  • Up to five temperature sensors (type DS18b20)
  • One microphone (3.5 mm jack input with 4 pins). Define which microphone you are using in the BEEP base app.
  • One temperature/humidity sensor (I2C BME280)
  • Two load cells for weight measurements (e.g. Bosche H40A 150kg) 

The PCB has a I2C connection where you can connect multiple I2C sensors. When you want to add your own (I2C) sensors, on top of the supported sensors as listed above, you need to write the corresponding code in the open source firmware. You can upload the new firmware to the BEEP base using the BEEP base app.

 

Note for customers outside the EU and Southern Africa: The LoRa chip in the BEEP PCB only complies with the LoRa frequency in Europe and Southern Africa. In other countries, you can use the PCB and all it's functions except the data transmission with the current LoRa chip.
