TL;DR:
This post details the materials, sensors, and motivation behind the atmospheric measurement board used in the FIELD (Frequency & Intensity Experiments on Leaf Development) project. In total, the board utilizes NN sensors:
Tools:
- FNIRSI Soldering station: Soldering station with numerous features & helping hands [Link]
- Solder smoke absorber: Efficiently removes solder smoke from the workplace [Link]
- Heat-shrink solder kit: Kit to add heat-shrinking sleeves around metal connections [Link]
Hardware:
- ESP-32: Sends the AD9833 its configuration over SPI ,telling it waveform type (sine) and frequency [Link]
- AD9833: Handles programmable waveform generation [Link]
- SPH0641LU4H-1: The ultrasonic microphone to measure output from the ultrasonic speaker [Link]
- METOOT: The dimensions of the watermelon, including its ability to stand upright. [Link]
