Hello everyone and welcome back to another Friday Product Post here at SparkFun Electronics. We have quite a few new products to get through this week and, if you didn't see our blog yesterday, we have four new PIR Breakout Boards that utilize the EKM-series PIR sensor from Panasonic®. Following that, we are going to look at our new SparkFun Original Ultrasonic Distance Sensor, and then a new ESP32 WROOM Module. Let's jump in and take a closer look!
The SparkFun PIR Breakouts (170uA and 1uA) and Qwiic PIRs (170uA and 1uA) use two versions of the EKM-series PIR sensors from Panasonic® to offer low profile motion-sensing options over I2C for both battery-powered and continuously-powered applications. The Qwiic versions of these PIR breakouts feature an ATTiny84, with firmware that handles monitoring the sensor's output signal, debouncing that signal along with a configurable interrupt, and translating it all to the I2C interface (which means it's easy to add a PIR to an existing Qwiic/I2C project).
Is your project linked to environmental protection, awareness or study, or to protecting human life? Perhaps you are developing a wildlife tracker, ocean buoy, environmental monitoring system or need to transfer emergency medical information? Do you need to be able to transmit and receive data anywhere? If so, this is the product for you! Our ARGOS Satellite Transceiver Shield allows you to send and receive short bursts of data via the ARGOS satellite network, anywhere on Earth including the polar regions.
You may be familiar with the classic HC-SR04 distance sensor - it's great for providing non-contact distance readings from 2 cm to 400 cm. The SparkFun Qwiic Ultrasonic Distance Sensor improves on the classic by adding a pair of Qwiic connectors to it, so now you can communicate over I2C and daisy chain any other Qwiic product of your choosing.
The ESP32-WROOM-32E is a powerful, generic Wi-Fi+BT+BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding.
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! Please be safe out there, be kind to one another, and we'll see you next week with even more new products!
