Barometric Pressure Sensor - BMP180
Price: $10.33
Availability: Stocked
Sparkfun Item #: COM-11823 -

"The BMP180 is a high-precision, ultra-low power digital barometer. It offers a measuring range of 300 to 1100 hPa with an absolute accuracy of down to 0.02 hPa. The BMP185 is based on piezo-resistive technology for EMC robustness, high accuracy and linearity as well as long term stability. What makes this sensor great is that it is nearly identical to its former rev, the BMP085! This sensor supports a voltage supply between 1.8 and 3.6VDC. It is designed to be connected directly to a...

Op-Amp (Thru-Hole) - LM358
Price: $1.65
Availability: Stocked-NoBackOrder
Sparkfun Item #: COM-09456 -

"The LM358 is a great, easy-to-use dual-channel opamp. Opamps have so many applications we figured we should probably carry at least one in a DIP package. LM358 applications include transducer amplifiers, DC gain blocks and all the conventional opamp circuits. If you’re looking for a good, standard opamp the LM358 should fill most of your needs. It can handle a supply of 3-32VDC and source up to 20mA per channel. This opamp is great if you need to operate two individual opamps from a...
