We could talk about how the Zinc used in these nuts is only from the finest old-growth Zinc trees from across the globe and is hand picked only at the peak of the season. Or how they are expertly hand-ground by a 6th generation master grinder. And how every nut passes a rigorous 19-point inspection process at each step of the process. And how each nut's dimensional variations can only be measured on the sub-atomic level. We could say all that, but it would be a lie. These are standard 4-40...

    This is a waterproofed version of the DS18B20 Temperature sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125 degree, the cable is jacketed in PVC so we suggest keeping it under 100 degree. Because they are digital, you don't get any signal degradation even over long distances! The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and...

The MAX31820 ambient temperature sensor provides 9-bit to 12-bit Celsius temperature measurements with ±0.5°C accuracy over a +10°C to +45°C temperature range. Over its entire -55°C to +125°C operating range, the device has ±2.0°C accuracy. The device communicates over a one-wire bus that, by definition, requires only one data line (and ground) for communication with a central microprocessor. In addition, the device can derive power directly from the data line, eliminating the need for an...

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the 'alarm' pin will go low. This unit works great from 5 to 12V (datasheet shows 12V). You can also install a jumper wire past the 5V regulator on board to make this unit work at 3.3V. Sensor uses 1.6mA@3.3V. The alarm pin is an open collector meaning you will need a pull up resistor on the alarm pin. The open drain setup allows...
