=Summary of the last meeting=

STM32 hands-on

 * "ping pong" test between two STM32 with LoRa daughterboard
 * Test of the X-NUCLEO-IKS01A1 card's sensors

Instrumentation of the water pocket

 * Ideas about the choice of the sensor : use a ST "Time of Flight"(ToF) sensor, low cost camera compatible with the stm 32 ?
 * Researches about the ST's "Time of Flight" laser sensor (Reference chosen : VL53L0X) : sensibility, range, precision, cost...
 * Researches about the communcation between the ToF sensor and the STM32 board : via I2C pins
 * Brainstorming about sensor stand (size, materials, how to attach the sensor on it and the stand on the ground)
 * Brainstorming about the pumps' control
 * Choice of the stm32's power supply : a simple USB charger (220V to 5V), as we have acces to power outlets
