Electric Imp impExplorer Kit

The Electric Imp impExplorer Kit is the ideal basis for building self-contained connected devices. It includes not only a trio of temperature and humidity, motion, and pressure sensors, but also an RGB LED for visible feedback. In addition, it provides Grove System headers for expansions. Two of these connectors are intended for peripherals, the others for analog and/or digital devices.

Power

The impExplorer Kit can be powered either by a standard mini USB cable fed from an AC adaptor or a suitable ie. powered USB port on another device, such as a computer, TV or set-top box. The Kit’s USB port is wired for power only no data can be exchanged this way. The underside of the impExplorer Kit is fitted with a holder for three AA batteries. If you choose to fit rechargeable cells, please be aware that the impExplorer Kit does not include charge management circuitry your cells will need to be recharged externally. The impExplorer Kit will always use USB power, if present, in preference to battery power.

Power Gate

The impExplorer Kit is power gated, with control of the gate applied to hardware.pin1. To support high-power 5V peripherals, such as the RGB LED, and to make use of the Grove Analog/Digital ports, make sure you include the following line at the start of your device code:
hardware.pin1.configure DIGITAL_OUT, 1 ;

Note Because the impExplorer Kit’s three built-in sensors use hardware.pin1 as their interrupt trigger, you will not be able to use this aspect of their functionality if you also wish to make use of the RGB LED and/or Grove Analog/Digital ports.

impExplorer Kit Sensors

The impExplorer Kit incorporates three components for environment sensing:

Sensor

Measured Quantity

Address Datasheet 8-bit

HTS221

Temperature and humidity
0xBE

Link

Motion in LIS2DH12
three axes
0x32

Link

LPS22HB Air pressure 0xB8

Link

All three sensors operate over and connect to the on-board imp001’s hardware.i2c89 bus. In addition, each sensor has an interrupt line used for signalling critical value alerts. All of these lines connect to the imp001’s hardware.pin1 an interrupt from any of the sensors will cause hardware.pin1 to be high.

All of the sensors can be easily accessed in application code using the following Electric Imp libraries:
#require "HTS221.class.nut:1.0.0" #require "LPS22HB.class.nut:1.0.0" #require "LIS3DH.class.nut:1.3.0"

Note The LIS2DH12 intentionally makes use of the LIS3DH library as these two devices are functionally equivalent.

RGB LED

The impExplorer Kit’s RGB LED is a WS2812 device which can be accessed via the imp001’s hardware.spi257 bus set to MSB_FIRST mode and a speed of 7500KB/s. Only imp001 pin 7 is actually used in this role, so it is possible to make use of the Grove Analo/Digital ports see below , which operate from hardware.pin2 and hardware.pin5. It you are making use of the LED and either of these pins with Grove sensors, you should configure the LED first and then configure the Grove sensors.

The LED is best driven in application code via Electric Imp’s WS2812 library add #require "WS2812.class.nut:2.0.2"
to the top of your device code. You will also need to add the following line at the start of your device code hardware.pin1.configure DIGITAL_OUT, 1 ;
