I/O Accessories Kit for I/O Learning Card for Raspberry Pi

FEATURES I/O Accessories Kit for I/O Learning Card for Raspberry Pi ON-OFF-ON Switch Thermistor Photoresistor Potentiometer RS485 Temperature and Humidity Sensor Micromotor DESCRIPTION Designed orginally as companion to the I/O Learning Card (no longer in production), this kit can be used to experiment with and I/O HAT with analog and digital inputs. 1. ON-OFF-ON SWITCH The switch can be used to demonstrate how to read the contact closure inputs.   2. THERMISTOR The thermistor can be used to measure ambient temperature using the 0-10V input.  3. PHOTORESISTOR The photoresistor will let you measure light. You can use it to turn lights on at dark, to see when somebody enters a room, or for any application which needs light. It can be read also with the 0-10V input. 4. POTENTIOMETER Used also with the 0-10V input, the potentiometer will let you simulate the analog output of a sensor which you can display in Node-RED. 5. RS485 TEMPERATURE AND HUMIDITY SENSOR The sensor requires two connectors, one with 2 pins going to the RS485 data port and one with 3 pins going into the 4-20mA input port for power. Use Node-RED to read ambient temperature and humidity. 6. MICROMOTOR Plug the micromotor into the MOTOR port and use Node-RED to control the speed and direction. Use it with a SERVO connected to the 6 pin header (SERVO not included) and build a small robot driven by Raspberry Pi.
