Add-on sensors, etc
$1.00 to $8.00
These accessories can only be added to orders for the SkyPod Kit, Nano Logger Kit, or Mini Pearl Logger Kit (no shipping costs are included here). If you have ordered those kits, add as many of these to your order as you wish (add them to your cart one at a time).
Most of the sensors below are I2C sensors and each includes a 10 cm four wire cable with DuPont connectors for easy attachment to the Nano Logger. Male headers are already soldered to each sensor. The DS18B20 is a one wire sensor.

BME280 3.3v: $6.50 I2C sensor for barometric pressure, temperature and humidity. 3.3 volt operation only (power from the 3V3 pin on the Nano Data Logger). The board does not include a voltage regulator, and this version might use less power. Tutorial for similar module. Research notes.
BME280 5v: $6.50 I2C sensor for barometric pressure, temperature and humidity. Either 3.3 volt or 5 volt operation. The board includes a voltage regulator, and this version might use more power. Tutorial for similar module. Research notes.
MMA8451: $4.00 I2C three axis accelerometer. Detects motion or tilt and records direction of movement. Either 3.3 volt or 5 volt operation. Tutorial for similar module.
DS18B20: $2.50 One-wire temperature sensor. Waterproof and ready for outdoor use. Cable is 36" long. Includes a resistor which must be included in the circuit. Either 3.3 volt or 5 volt operation. Getting started info. Research notes.
LCD display: $6.50 A two line by 16 character LCD to display sensor results in real time. Bright blue backlight and white letters. Includes attached backpack PCB which converts the display to an I2C device. Includes 20 cm four-wire cable with DuPont connectors. No soldering required. 5 volt operation only (so not recommended for the Mini Pearl Logger). Tutorial for similar module. Research notes at Public Lab. Here are more details.
USB to TTL Converter: $3.50 FTDI FT232RL USB to TTL Serial Converter Adapter. The Arduino Pro Mini does not have a USB port, so a device like this is needed to load programs onto the Pro Mini. Set jumper to 3.3V for use with the Pro Mini. A 6-wire Dupont cable is included to connect the pins on the Pro Mini with the FTDI adapter pins.
DuPont wires: $1.00 Three 20cm four-wire cables with individual female DuPont connectors on each wire. Colors vary.
