<p>I realize this is kind of geeky, but I&#39;m always interested in &quot;failure modes&quot; of things. So, what would cause a persistent perfectly circular black spot in the middle of what looks to be a perfectly good display? (This has been here for weeks on a local gas pump. It&#39;s always there regardless of what&#39;s being shown).</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@wingo" class="u-url mention">@<span>wingo</span></a></span> the sensors differ a bit between various models, but basically it&#39;s power hungry because NDIR requires a lightbulb (incandescent. yes really. in the SCD30 thats what they use) and thermoacostic requires a heater</p><p>having eink, low power wifi/zigbee helps but your floor is set by the co2 sensor</p><p>for particles, i think it uses a tiny fan</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> But do they take it _seriously_</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> so you think it’s really just down to collection frequency? i wonder if they are also treating 4 years as including some kind of standby mode where frequency is 0</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@wingo" class="u-url mention">@<span>wingo</span></a></span> this is true but even the sensor that keeps the leds mostly off that i have (and has no lcds) basically requires mains</p>
