Maybe you are not germ-phobic, but the current epidemic has made it necessary for us to develop a daily disinfecting habit. If you are willing to give your keys, glasses, pens and even cellphones a sanitizer bath, why not your  two-way radios ? After all, germs do not discriminate. Here is how I suggest you should disinfect your two-way radios: Disinfect your walkie talkie with isopropyl alcohol wipes. Do not use or allow moisture into any of the radio’s openings; If you don’t have wipes, use a clean microfiber cloth and diluted alcohol (60%water& 40% alcohol). Remember to dry radio surfaces immediately after disinfecting. After you are done disinfecting, leave your radio in a ventilated environment to dry.

Smart thermostats  are increasingly becoming a part of the larger smart home landscape. The "Works with Alexa" initiative makes it possible for folks to integrate the thermostat, the T29UTW-7-WIFI (TY) is worked with Amazon Alexa. That means you can adjust your thermostat with a simple voice command: "Set my thermostat to 68," "What's the current temperature of my thermostat?"and so on.  But  smart thermostats  don't come cheap. You can snag a basic  7-day programmable thermostat  for less than 30 bucks. So, even if you're saving money on your energy bill, it might take awhile for the upfront cost to even out.But our T29UTW-7-WIFI (TY) is the highly cost effective in the  smart thermostats  list.  Heating and cooling plays a huge role in your connected home. It keeps you cozy, but there's a definite balance between comfort and saving money. While traditional thermostats can certainly do the job, the next generation of home heating and cooli...

Current transformer  is mainly composed of a primary winding,a secondary winding and an iron core, and there is insulation among the primary, secondary and iron cores. ​ In order to improve the accuracy of the current transformer, the error of the current transformer is generally compensated.In addition to the above-mentioned primary and secondary windings and cores, some also wound auxiliary coils or added auxiliary cores. The core of the current transformer has two forms: square and circular. At the beginning of the ring-shaped iron core, silicon steel sheets are used to punch the ring pieces, which are stacked one by one. Now most of them have been directly rolled with silicon steel strips. The advantages of this iron core are that it has no air gap, high magnetic properties, and is easy to roll. If the winding is evenly wound, the magnetic leakage is small. Therefore, all precision current  transformers above class 0.2 use this kind of tape wound core. Its disadvantage is ...

Two-way radios  have gained favors with a wide range of users since its invention. People prefer two-way radios to other means of communications due to their manifold advantages. So, what are the main advantages of a two-way radio? 1)  Fast Communications And Stable Networks With a two-way radio, it is push-to-talk. The transmitting rate is incredibly fast. The moment you transmit, the other user receives without having to pick up the call. This is way more efficient than a cellphone. As for stability, when disasters strike and public networks are paralyzed, communications will solely rely on private networks and two-way radios. 2)  Excellent Audio And Great Anti-interference A quality two-way radio will normally incorporate a combination of communication technologies, such as advanced vocoder, signal processor, encryption, etc., to deliver a pleasant user experience. When it comes to audio quality and anti-interference, a two-way radio is usually superior to...

C-wire requirement Most  smart thermostats  require more electrical power than a set of batteries can provide. Fortunately, they don’t require so much power than they need to be plugged into the wall. They rely instead on low-voltage power provided by your HVAC system. Many smart thermostats require the presence of a dedicated C (common) wire for this purpose, while others can siphon electricity from another source, typically the R (power) wire. But the latter practice is known to cause problems with some HVAC systems, including permanent damage. If you pull out your existing thermostat to install a smart model and find no C wire connected to it, look inside the wall to see if there’s one that hasn’t been connected. If there’s no C wire, our advice is to have one installed. Only a couple of the thermostats reviewed here require a C wire, but all the manufacturers highly recommend using one. Saswell recommend to use our Electric Control Module if no C wire. Ease of insta...
