' Product Overview ' Made in Texas The EPSLED-80-STB-SOL-60C-ILS-20C-C1D2-20C from Larson Electronics is a Solar Powered Explosion Proof LED Indicator Light that is a reliable lighting solution for remote areas and standalone applications where connection to external power is either impractical or unavailable

Carbon Monoxide Sensor - MQ-7 SAFECROSS pdf) Power DiodeThis is a simple to use [Carbon Monoxide (CO)](http: en. wikipedia. org wiki Carbon_monoxide) sensor, suitable for sensing CO concentrations in the air. The MQ 7 can detect CO gas concentrations anywhere from 10 to 500ppm. This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the
