Connect a DHT11 Temperature Sensor and run:
DATA -> GPIO4
VCC -> VUSB (VIN is OK if using battery(3.7-42V) but not 3V3 as not high enough)
GND -> GND
HC-SR04 Thing
This example creates a Thing that exposes the current distance reading or the HC-SR04 ultrasonic
distance sensor and also displays the distance locally.
Connect an HC-SR04 Ultrasonic Distance Sensor and run:
TRIG -> GPIO2
ECHO -> GPIO4
VCC -> VUSB
GND -> GND (VIN is OK if using battery(3.7-42V) but not 3V3 as not high enough)
HC-SR501 PIR Thing This example creates a motion sensor Thing that triggers on movement. It sets the on-board
LED on triggering and updates the mozilla-iot interface appropriately. Connect an HC-SR501 Passive Infrared
Sensor or any similar device and run:
OUT -> GPIO4
VCC -> VUSB (Typically VIN is OK if using battery(3.7-42V) but not 3V3 as not
˓ →
high enough)
GND -> GND
Touch Thing This example creates a touch switch Thing that triggers when one of the capacitive touch pins on the
ESP32 are touched. It sets the on-board LED on triggering and updates the mozilla-iot interface appropriately.
Connect a wire to GPIO4 and run.
Calculator Thing
This example is a simple integer calculator that creates a Thing that exposes the two numbers, the
last function and the result. It requires the IoT-Bus display.
Door Sensor Thing This example shows how to use a typical magnetic door sensor. Just connect one side of the
contacts to GPIO4 and the other to GND. When the contacts are open the door sensor will show open in the
mozilla interface and when they are shut the door will show shut.
Relay Thing This example uses an IoT-Bus relay board together with an IoT-Bus Io processor to expose the relay
status and to enable the user to change through your mozilla-iot domain.
Relay Display & Touch Switch Thing In this second relay example the current status of the relay is also shown on
the display. The touchscreen is enabled so it can be switched on and off locally. The status will be reflected by
mozilla-iot.
