Inputs

Input modules sense the outside would and feed the result into the picXplorer controller. They have a three way connector on their right hand side and are identified by a number. Use the following chooser chart to identify suitable modules for your application.

Id	Function	Description	Module type
1	Push button	When the button is pressed a high signal is output	Digital
2	Toggle switch	A high or low signal is output depending on the switch position	Digital
3	Preset potentiometer	A high or low signal is output depending on the angular position of the control. When used with an analogue input, the output signal gives a measure of angular position.	Analogue/digital
4	Reed switch	A high signal is output when a magnet is brought near	Digital
5	Tilt switch	A low signal is output when the left-hand side is lowered	Digital
6	Temperature sensor	PICAXE compatible temperature sensor	Digital
7	Touch memory	Produces a unique code when touch memory is connected	Digital
8	Infra-red receiver	Receiver for use with the PICAXE infra-red commands	Digital
9	Matrix keypad	When scanned, a pressed key causes a high signal on the relevant input. This module must be used in conjunction with output module	Digital
10	Light dependent resistor	A high signal is output in light. When used with an analogue input, the output signal gives a measure of light intensity	Analogue/digital
11	Slotted opto sensor	A low signal is output when an opaque object is put in the gap. When used with an analogue input, the output signal gives a measure of how much infra red is transmitted across the slot (gap)	Analogue/digital
12	Infra-red proximity switch	A high signal is output when an object is placed in front.	Digital
13	Adapter	Spaces out the input connections for wider input modules.
14	Accelerometer	Senses acceleration, or tilt	Analogue
15	Reflective opto sensor	A high signal is output when an opaque object is placed in front of the LED and phototransistor	Analogue/digital
16	Potentiometer	A high or low signal is output depending on the angular position of the control. When used with an analogue input, the output signal gives a measure of angular position.	Analogue/digital
17	Slide switch	A high or low signal is output depending on the switch position	Digital
18	-	-	-
19	IR beam break sensor	A high signal is output when the infra-red beam is broken. The IR sensor on this module must be illuminated by the Modulated IR transmitter [26] placed in front (up to 4 metres away)	Digital
20	Hall sensor		Analogue
21	Octal switch	Supplies a high or low signal on up to eight outputs	Digital
22	External switch	Screw connector for connection to a switch on wires	Digital
23	Thermistor	Outputs a signal dependant on temperature. As the sensed temperature increases the output signal increases.	Analogue
24	Cable adapter	For connecting inputs modules remotely (on the end of a cable)	-
25	Power connector	For powering input modules remotely. For example the four bit IR transmitter	-
26	Sound switch	A low signal is output when sound is present. A small time delay is built into the sensor to stretch out the detection of short bursts of sound.	Digital
27	External sensor	Screw connector for external sensors on wires	Analogue/digital-
28	Microswitch	A high or low signal is output depending on the switch position	Digital
29	Modulated IR transmitter	Transmits a 38KHz modulated IR signal. For use with the infra-red beam break sensor [19].
