Oh, MicroPressure!
The Qwiic MicroPressure Sensor is now available, along with a slew of new Flirc products!
This week we have a few unique new products, starting with the SparkFun Qwiic MicroPressure Sensor for specialized and precise pressure sensing projects. After that we have three different products from Flirc, including a new case for the Raspberry Pi Zero, an IR USB widget, and a handy debugger. We round out the day with a SPDT relay!
Summer activities canceled? Welcome to SparkFun Summer Camp! We’ve got your classic camp fun covered online – with an electronics twist. Check out our activity schedule, and let’s have some fun! This is our last week of sales, and we're focusing on Machine Learning! Don't forget that you can get a free SparkFun Qwiic Pro Micro BoogieBoard with any purchase of $75 or more using promo code "BOOGIEBOARD20" (some restrictions apply).
Now onto our new products!
Pressure pushing down on me, Pressing down on you
The SparkFun Qwiic MicroPressure Sensor is a miniature breakout equipped with Honeywell's MPR Series piezoresistive silicon pressure sensor. This MicroPressure Sensor offers a wide pressure sensing range of 60mbar to 2.5bar and easy to read 24-bit digital I2C output, and can be calibrated and compensated over a specific temperature range for sensor offset, sensitivity, temperature effects, and non-linearity using an on-board Application Specific Integrated Circuit (ASIC). With its ultra-low power consumption and Qwiic ports, you've got yourself a power packed little sensor!
The Flirc Raspberry Pi Zero Case has an aluminium casing with a core heatsink and smooth top, offering silent, passive and efficient cooling combined with great looks. This case also comes with a thermal pad that can fit to the case heatsink core before fitting your Raspberry Pi Zero.
The Flirc USB allows you to pair any remote control with your computer or media center (including the Raspberry Pi)! Just walk through the super simple cross platform pairing application, and you're done. Use your previously paired remote with no additional software on any machine with Flirc.
The Flirc Jeff Probe is an open source in-application debugging tool for embedded microprocessors. It allows you see what is going on 'inside' an application running on an embedded microprocessor while it executes. It is able to control and examine the state of the target microprocessor using a JTAG or Serial Wire Debugging (SWD) port and on-chip debug logic provided by the microprocessor.
DC Power Relays interrupt high-capacity DC loads and high-voltage DC circuits in a compact, low-noise design. This SPDT relay's coil is rated up to 3V, with a maximum switching voltage of 250VAC, 125VDC. The contacts are rated up to 10A (@120VAC; 8A @30VDC).
That's it for this week! As always, we can't wait to see what you make! Shoot us a tweet @sparkfun, or let us know on Instagram or Facebook. We’d love to see what projects you’ve made!
Under "New Products" on the home page, I noticed two items that have appeared since last week (indeed, I don't recall seeing them yesterday) but weren't mentioned in today's blog, to wit, the latest version of SparkFun Qwiic Quad Relay and the Qwiic Multiport.
BTW, on the Quad Relay, there's an inconsistancy in the external power. The Description says it's rated 7-15V, but if you look closely at the photos, you can read "7-12V" near the power connector in the silk screen on both sides of the board. The "Features" talks about a dropout at ~7.4V, but doesn't mention the high limit. Also, I notice a third jumper marked "LED" that isn't mentioned in the Hookup Guide (or in the "Revision Changes"). And although the Hookup Guide is very clear on the external power supply being needed, IMHO it would be wise to also make that point in the Description -- many folks won't read the Hookup Guide in detail until they have "parts in hand", and may be disappointed by needing to scrounge up another wall wart that they could have included in their order.
Sorry about that. The product page specs and hookup guide were updated shortly after release. It should have that information. As a quick note, the dropout voltage ~7.4V was from the linear regulator. The latest input voltage is between 7V to 12V with the switching regulator circuit.
On the "Qwiic MicroPressure Sensor", nowhere in the Sparkfun web page does it say anything about measuring liquids. I did find this in the Datasheet: "Compatible with a variety of liquid media".
When I first saw it, I was thinking "compressor in my garage", but with a maximum pressure of 60psi for the sensor, and a max for the compressor of 120psi, that's out. (Even a tire pressure guage is out, as bicycles often have more than 60psi.) Next thought was maybe a hack to the coffee maker to sense the water level -- IoT send me a text message to remind me to set up my coffee maker before I go to bed, and every once in a while I put in the coffee and filter but forget to put in the water... oops... it's not "food safe", so that's out. :-(
Good catch! We've updated the product page with the pertinent information.
As a side note, we have actually been looking into the food safe version of this sensor. Stay tuned!
good
