You can add extra sensors to the PCB or the BEEP base. You can download the pdf file with the PCB connections as shown below. The system supports up to five temperature sensors (type DS18b20), You can add the extra sensors described above and configure them using the Android BEEP base app or the iOS BEEP base app.
Instructions to add sensors
You can add up to five temperature sensors to the BEEP base or BEEP PCB. There are two ways to connect an extra temperature sensor as described below. You also find instructions for connecting the humidity sensor.
Add temperature sensor (1) - connect additional cable(s) to the existing temperature sensor cable
Add temperature sensor (2) - connect temperature sensor in the PCB
|Connect LoRa antenna |
Connect the antenna IPX connector to the (ANT2) IPX socket on the bottom side of the PCB (see picture on the right. The LoRa antenna is the small black single wire).
|Connect load cell|
Open 5 screws of the load cell screw terminal (GND, A+, A-, GND, AVdd) on the top of the PCB by turning them 6x anti-clockwise.
Insert the ends of the load cell wires into the screw terminal.
Tighten the screws of the terminal until the wires are fixed.
Add humidity sensor
You can connect an extra Bosch BME280 temperature/humidity sensor to measure temperature and humidity inside or outside the hive. The humidity sensor is not included the the standard BEEP base.
The Bosch BME280 sensor is the purple chip on the left side of the PCB. You have to solder four cables to the four connection points in the sensor (see PCB overview above) and connect the other side of the cable to the PCB, as indicated in the picture.
The measurements are most reliable when the cable is up to one meter in length. You can put the sensor in a queen cage for protection and place it in the hive. In the BEEP app you will see the data under 'Measurements'.
Note: If you want to add your own (I2C) sensors, you can write the required code in the firmware for each sensor and upload this modified firmware via Bluetooth to the BEEP base.
