Component Box with electronic circuit board Rain sensor Wind speed sensor Solar panel Air temperature, relative humidity and air pressure sensor Leaf wetness sensor Soil temperature sensor Soil moisture sensor Meteobot Pro ✔ ✔ ✔ ✔ ✔ Depending on order ✔ ✔ ✔

1.3 Before you start the installation Please make sure you have: • Pole (e.g. metal tube) with diameter - 4-5 cm, and length - for Meteobot Pro: 3 m, for Meteobot Mini - 1,50 m; • Ladder; • Mobile phone with Android or iOS; • Data SIM card with SMS service enabled (no voice service is necessary); • Tools; • Hammer (for hammering the tube down in the soil); • Put the soil moisture sensor in clean water for 30 minutes;

2 Where to place the weather station? The weather station should be placed at a location with GSM coverage by your mobile operator. In order to get correct measurements, it is important to place the station: • On an even field and at a location, which is representative for the region; • If there is another object nearby (e.g. tree, building, etc.), the station should be installed at a distance at least 4 times longer than the height of the object. Example: if there is a 5-meter-tall tree nearby, the station should be at least 20 meters away from the tree. 2.1 Sensor for temperature, relative...

3 Installation In this section the installation of Meteobot Pro is described. Because Meteobot Mini has fewer components, they can be installed higher on the pole. Use a pole (metal tube) with diameter – 4-5 cm, and length – for Meteobot Pro: 3 m, for Meteobot Mini – 1,50 m; For Meteobot Pro: hammer the pole 1 m in the ground; for Meteobot Mini – 70 cm; IMPORTANT: Should be perfectly vertical! 3.2 Box with electronic circuit board • • • Install the box by clamping the two metal planks on its back to the pole with two hose clamps φ40-60 mm; For Meteobot Pro: the lower edge of the box should be...

v meteobot 3.3 Sensor for temperature, relative humidity and air pressure • Install the sensor using the lower hose clamp of the box; • The sensor should be facing North (opposite the box). 3.4 Solar panel • Install the solar panel by clamping it to the pole with a hose clamp; • For Meteobot Pro: above the box; the panel's lower edge should not touch the box; • For Meteobot Mini: on the same level with the box; • IMPORTANT: The panel should be facing South.

3.5 Rain sensor • Install the rain sensor by clamping it to the pole with two hose clamps; • For Meteobot Pro: the top of the sensor should be 5 cm above the top of the pole; • For Meteobot Mini: the top of the sensor should be 20 cm above the top of the pole; • The sensor should be facing East; • IMPORTANT: The upper opening of the sensor should be absolutely horizontal. 3.6 Wind speed sensor • Install the sensor at the top of the pole with a single hose clamp; • IMPORTANT: The sensor should be above all other sensors; • The sensor should be facing West.

3.7 Soil temperature sensor • Dig a hole in the ground to a desired depth and bury the sensor in it; • IMPORTANT: Compact the soil, so that no air remains around the sensor; • IMPORTANT: Do not thrust the sensor in the ground by force; • IMPORTANT: If there is a risk of rodents, place the sensor cable in a tube or another kind of protective wrapping. 3.8 Soil moisture sensor • IMPORTANT: Put the sensor in clean water for 30 minutes before installation; • The sensor should be placed in the plant's roots; • The location of the sensor should be representative of the field: o The soil conditions...

The sensor provides correct readings for about 2 years, depending on conditions. Replace it after this period.

3.9 Leaf wetness sensor • Fasten the sensor with cable ties near the plant, whose leaf wetness will be measured; • The incline relative to the ground should be about 30o; • IMPORTANT: If the sensor gets dirty, clean it with a soft wet cloth; • IMPORTANT: Be careful not to scratch the sensor during installation or cleaning. 3.10 Connecting the cables • Open the lid of the box with a straight screwdriver (-); • Insert the sensor and panel cables in the box through the cable glands (the round openings) in the lower end of the box; • IMPORTANT: Only one cable should pass through a cable gland. Otherwise...

3.11 Cable connection scheme radiation sensor Extension board RED GREEN WIND WIND SOIL TEMPI 1. Install the SIM card in your mobile phone and disable the SIM PIN code; 2. Install the SIM card in the SIM card slot on the electronic circuit board; 3. Place the cable ends in the corresponding socket on the electronic circuit board, as described on the scheme above. Then screw the socket bolts with a small screwdriver.; 3.1. IMPORTANT: Connect the air temperature, relative humidity and air pressure sensor; the leaf wetness sensor, and the soil temperature sensor to the electronic circuit board observing...

4 Diagnostics There are three light emitting diodes (LEDs) on the electronic circuit board: • Red and green – on the right; • Red – on the left. When power is supplied (i.e. after connecting the battery) the red and greed LEDs on the right glow continually; After several seconds the red LED on the right goes out, the green LED on the right glows continually, and the red LED on the left start blinking quickly; When the weather station connects to the GSM network, the green LED on the right goes out, and the red LED on the left starts blinking at longer intervals. When the weather station starts...
