Dendrometer LoRaWAN Node Description A dendrometer is used to measure the time varying stem diameter of a tree. We built a LoRaWAN data transmission module which we connects a commercial dentrometer (Ecotech) to in order to transfer current data in real-time wirelessly. This prototype consists of a custom-made PCB and a commercial housing with molded water proof cable glands.

Plant Pot Scale Goal: Development of Wifi or BLE enabled scale to measure the weight of plant pots for an experiment of Anna-Lea. Anna-Lea's Irrigation Experiment in the Greenhouse on Campus Kleve. Weight Range Estimation The intended pot size has $d = 20\, \mathrm{cm}$$V = 7.5\, \mathrm{L}$$\rho_s=1.6\, \mathrm{kg/L}$$\eta = 40\,\%$$\rho_w=1\, \mathrm{kg/L}$$m$$m_s$$m_w$$m = m_s + m_w = \rho_s \cdot V + \eta \cdot \rho_W \cdot V = (\rho_s + \eta \cdot \rho_W) \cdot V = (1.6 + 0.4\cdot 1)…
