This document discusses using sensors and an Arduino board to collect data from a greenhouse and send it to the IBM IoT Cloud platform. An Arduino board with a DHT11 temperature and humidity sensor collects data from a greenhouse and sends it via WiFi or Ethernet to the IBM IoT Cloud using the MQTT protocol. The document tests collecting sensor data locally and sending it to the cloud.
