Motor / Switch Channel Locations:

The Adosia SPACE IO board has two (2) independent DC motor switch channels which can be used to drive a variety of motors, valves, switches and pumps. Each channel is diode-protected and can drive loads up to ~450mA at 12V (transistors rated ~600mA):

motor / switch channel #1
motor / switch channel #2

Motor / Switch Channel Component Options:


Digital IO Channel Locations:

The Adosia SPACE IO board has two (2) independent digital IO channels to drive general digital input sensors / signals or output signals which can be used with a variety of components:

digital io channel #1
digital io channel #2

Digital IO Component Options:


Application-Specific Input Sensor Channel Locations:

The Adosia SPACE IO board has two (2) independent channels for application-specific input sensors requiring an external 4.7kΩ pullup resistor

app-specific input channel #1
app-specific input channel #2

Application-Specific Input Sensor Component Options:


Analog Sensor Channel Location:

The Adosia SPACE IO board has one (1) channel to connect an analog sensor. The on-board connector supplies 5V to the sensor, and can support sensors requiring a 5V input supply voltage which outputs up to 3.3V.

connect 5V analog sensors directly to the analog connector with the black (ground) wire positioned towards the top edge of the board and the blue (analog) wire positioned towards the bottom of the board

analog sensor channel

Analog Sensor Component Options:

*some sensors such as the ambient light sensor must be connected using a 3.3V supply pin instead of 5V to ensure the sensor output does not exceed 3.3V

Relays components that can be tied to digital outputs and are used to switch higher power AC devices on and off. Relays greatly expand the capability of any system and can be activated using Digital IO #1 and/or Digital IO #2 set to General Digital Output when editing a device profile.

The relay module Adosia ships is activated using a LOW signal profile setting mode, and each relay can switch up to 15A at 120VAC or 10A at 220VAC. Supply 5V to the relay module allows the 3.3V output signals from the SPACE IO board to trigger the relay.


The relay module Adosia ships has 4 pins:

Adosia IoT devices are programmed using device profiles that have been preconfigured for specific use cases by an Adosia platform user. You can create your own device operating profiles or purchase device profiles from other Adosia users. Device profiles enable multiple devices assigned the same profile to be easily managed. IoT device profiles can also be scheduled to dynamically activate at a specific desired time of day.

There are 3 main areas you can customize when programming the WiFi board:

motor / switch channels
digital input sensors / outputs
app-specific sensors and analog

Each component plug-in or socket area of the board is highlighted by a red box on the board image displayed when specifying specific operating parameters for each area or pin of the board.

IMPORTANT - Once the deploy button has been clicked for each area, devices assigned to the newly configured profile will be set to update the next time each respective device checks in with Adosia's servers.


1. Motor / Switch Channels:

The Adosia SPACE IO board has two (2) diode-protected switch channels to safely drive components based on brushless DC motors and solenoids, such as pumps, motors, valves, locks. Each of these channels can each drive loads of up to ~450mA at 12V DC (transistors are rated ~600mA)


Motor / Switch Channel Operating Modes:


Motor / Switch Configuration Examples:

hydroponics system cycle setup
hydroponics system reservoir air pump
attach trigger to activate water pump
attach trigger to unlock deadbolt
schedule LED strip lighting to start daily
open valve 2 minutes 4 times per day


2. Digital IO Channels:

The Adosia SPACE IO board has two (2) channels dedicated to digital IO. These channels are rated at 3.3V can be configured to either digital input mode, digital output mode or motion detector. The maximum voltage on the pins is 3.3V (input or output).


Digital IO - Output Operating Modes:


Digital IO - Output Mode Examples:

use relay to schedule lighting at 8am for 10 hours
run large water pump 5 minutes 4 times per day
set relay to cycle 2 minutes on / 20 minutes off


Digital IO - Motion Detector Modes:


Digital IO - Motion Detector Examples:

set motion detect to trigger component group
delay group trigger 10 seconds after motion detect
triggers after 3 motion detects within 20 seconds


Digital IO - Input Operating Modes:

Digital IO channels utilize an internal pullup resistor when set to digital input mode, meaning the relevant pin will evaluate HIGH when no sensor is connected. To trigger an input on high, the attached input component (sensor or peripheral) should pull the signal low during non-triggering states.


Digital IO - Input Mode Examples:

set push-button to open lock after 3 second delay
set tilt sensor input to send alert when moved
set magnetic switch trigger buzzer alarm


3. Application-Specific & Analog Sensors:

The Adosia SPACE IO board has two (2) channels dedicated to application-specific sensors and supports one (1) analog sensor. Current application-specific sensors supported include water level sensor switches and temperature sensors. Current analog sensors supported include sensors to detect soil moisture level, natural gas levels, sound levels or ambient light levels.


Water Level Sensor Switch:

Water level sensor switches can be used to monitor state, to protect components (or component groups) from operating when triggered, and can trigger separate components (or component groups) into action whenever triggered.

normal switch logic
inverted switch logic


Water Level Sensor Switch Examples:

level switch protecting pumps with alert on trigger
level switch protects group & refills reservoir
level switch protecting + refill trigger + alert


Temperature Sensor:


Temperature Sensor Examples:

trigger component group on high temperature
trigger individual component on low temp
trigger alert only on high temperature

To calibrate an analog sensor you will first need to use that sensor to measure the maximum and minimum readings that sensor could possibly measure when operating.
