Description: The ML8511 breakout is an easy to use ultraviolet light sensor. The MP8511 UV (ultraviolet) Sensor works by outputing an analog signal in relation to the amount of UV light that’s detected. This breakout can be very handy in creating devices that warn the user of sunburn or detect the UV index as it relates to weather conditions...more detail given below

This breakout can be very handy in creating devices that warn the user of sunburn or detect the UV index as it relates to weather conditions.
This sensor detects 280-390nm light most effectively. This is categorized as part of the UVB (burning rays) spectrum and most of the UVA (tanning rays) spectrum. It outputs a analog voltage that is linearly related to the measured UV intensity (mW/cm2). If your microcontroller can do an analog to digital signal conversion then you can detect the level of UV!

Highly accurate, digital laser photo tachometer: measure rotational speed with a visible red light beam from a powerful LED. It's a great tool to measure the RPM of motors and machine parts, the speed of a lathe or milling machine for metal or wood working, or for HVAC applications to measure fan speed. To take the measurement, apply a reflective mark (included in package) onto the target object, aim the laser beam at the mark, the RPM displays on the LCD screen. Size : 180 x 72 x 37 mm (7.0 x 2.8 x 1.5").
Description: This is a piezoresistive force sensor from Tekscan. The harder you press, the lower the sensor’s resistance. Pressing hard, the resistance changes from infinite to ~300k. The sensor itself is thin and flexible, but the resistance does not change while being flexed. Resistance changes only when pressure is applied to the round area at the end ...more detail given below
