The LoRa module also echos the message to its serial port for interfacing with other systems (more about that in the next post). When one is received, an LED and/or servo are activated. Whenever the state of the connected switch changes, the transmitter sends a short string of text: “1” indicating open or “0” for closed, followed by a space then the battery voltage. We’re powering it from the solar panel’s two 2600 mAh batteries, enough to power the module for 500+ hours. In that state it draws only around 10 mA. The transmitter spends most of its time in low power mode with the radio sleeping. The project is described below in detail below in case you want to build something similar Project SummaryĪ pair of LoRa radios is used for this project, one as transmitter and the other as receiver. Interior of solar panel before any modification The only deficiency I see with this product is that it lacks an O-ring or other means of weatherproofing, although the Amazon product page claims it is IP65 splash resistant. One screw opens it up and there’s plenty of room inside to add your own circuitry inside. The device has a weatherproof enclosure, two user-replaceable 2200 mAh batteries and charging circuit. I found a $30 solar floodlight on Amazon that is perfect for this and would be for many other IoT (Internet of Things) projects. LoRa modules are inexpensive and consume very little power. Unobstructed range can exceed several miles. LoRa (Long Distance Radio) works great for sending short data packets great distances. I cobbled together the perfect solution using a repurposed solar-powered floodlight and LoRa transmitter/receiver pair. Running hundreds of feet of cable seemed like an expensive and impractical means of solving the problem.
There is no source of power near the mailbox.

And the distance exceeds the range of commercially available Bluetooth and WiFi solutions. There are simple mechanical devices that set a visible flag when a mailbox is opened but ours is too far from the house to see. So I devised a means of getting an alert when the mail is delivered. But it’s over 100 yards away from the house, so it’s nice to know when there’s actually something in it to collect. One of the daily events that’s taken on new importance is walking down to the mailbox. In these pandemic times of limited mobility, I become more like a dog every day: looking forward with great enthusiasm to meals, walks and car rides. You’ve got mail!
